Answer:
-4
Step-by-step explanation:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}=\frac{0-(-8)}{0-2}=\frac{8}{-2}=-4[/tex]
The slope of the line that passes through the points (2, -8) and the origin is calculated using the formula m = rise/run, which gives -4.
Explanation:In this Mathematics problem, we are asked to find the slope of the line that passes through two points using the formula m = rise/run, where 'm' is the slope. The points provided are (2, -8) and the origin, which is (0, 0).
To find the slope (rise/run), we can subtract the y-values (rise) and the x-values (run) of the two points, respectively. So, the formula becomes: m = (-8 - 0) / (2 - 0) => m = -8/2 = -4.
Therefore, the slope of the line that passes through the points (2, -8) and the origin is -4.

Follow the instructions below to show two different ways of filling a square that has sided of length a + b with triangles and squared without gaps or overlaps.
The proofing for the triangle is illustrated below.
How to illustrate the information?The proofing for a² + b² = c² in the triangle is illustrated.
It should be noted that the longest side in the triangle is the hypothenuse. The hypothenuse is gotten by finding the square root of the opposite and the adjacent.
Therefore, a² + b² = c²
Let's say a = 3 and b = 4, the value of c will be:
c² = a² + b²
c² = 3² + 4²
c² = 9 + 16
c² = 25
c = ✓25

What is the value of modulus?'Modulus' exists a Latin word, which signifies 'measure'. Absolute value is commonly referred to as numeric value or magnitude. The absolute value designates only the numeric value and does not contain the sign of the numeric value. The modulus of any vector quantity exists ever taken as positive and exists in its absolute value.
The absolute value (or modulus) | x | of a real number x stands as the non-negative value of x without regard to its sign.
For example, the absolute value of 5 stands at 5, and the absolute value of −5 exists also at 5. The absolute value of a number may be considered as its distance from zero along a real number line.

The drama class sold

The solution is
Solving a system of equations we will see that they sold 80 adult tickets.
how many adult tickets were sold?
To solve this, we need to solve a system of equations. To define said systems of equations, we first need to define the variables, we will use:
x = adult tickets sold.y = student tickets sold.They sold 20 more adult tickets than student tickets, then:
x = y + 20
And they collected a total of $880, then:
x*$8 + y*$4 = $880
The the system of equations is:
x = y + 20
x*$8 + y*$4 = $880
Isolating y on the first equation we get:
y = x - 20
Replacing that on the other equation we get:
x*$8 + (x - 20)*$4 = $880
Now let's solve that for x.
x*$12 - $80 = $880

Answer:
1.The slope intercept- form of the function is:
y = x -2
2.The predicted length of the vine after 53 days is 51 cm.
Step-by-step explanation:
The slope is the [tex]\frac{change in length}{change in days}[/tex]
In the table, every time that the length increased by 5, the days also increased by 5. 5/5 = 1
Now we have to find the y-intercept, we can use the slope and one of the points that we know to do this. Let's use the first point (5,3). This is in the form (x,y).
y = mx + b
3 = (1)(5) + b
3 = 5 + b Subtract both sides by 5
-2 = b Now we can write the equation
y = mx + b
y = x -2. Plug 53 in for x and you will find your second answer.
y = 53 - 2
y = 51
1. The function's slope intercept form is y = x -2.
2. The vine should be 51 cm long in length after 53 days.
Determining the Slope Intercept Form:
The slope is given as,
m = (Change in length) / (Change in days)
In the table, it can be seen that,
The days climbed by 5 for every 5 that the length did as well [10-5 = 8-3 = 5].
∴ Slope, m =5/5 = 1
We may use the slope and one of the points we are familiar with to help us find the y-intercept. Utilizing the first point (5,3), this is how it looks for the point (x, y),
y = mx + c ..... (1)
3 = (1)(5) + c
3 = 5 + c
Subtract 5 from both sides to get c.
c = -2
Hence, from (1), the slope intercept form is given as,
y = x - 2 ...... (2)
Predicting the Vine Length:
Since x represents the number of days, put x = 53 in equation (2) to predict the vine length after 53 days.
y = (53) -2
y = 51 cm
Thus, the length of vine after 53 days would be 51 cm.
