The graph of 2x - 3y > 18 is a dotted line passing through the intercepts (9, 0) and (0, -6).
What is Linear Inequalities?Linear inequalities are defined as those expressions which are connected by inequality signs like >, <, ≤, ≥ and ≠ and the value of the exponent of the variable is 1.
Given inequality is 2x - 3y > 18.
Since the inequality sign does not include =, the line will be dotted.
Since the equation is linear, graph will be a line.
Consider 2x - 3y = 18
When x = 0, -3y = 18 or y = -6
y intercept is -6.
When y = 0, 2x = 18 0r x = 9
x intercept is 9.
The line touches the X axis at (9, 0) and the Y axis at (0, -6).
At origin (0, 0), the inequality 0 > 18 is not true.
Hence the shading of the graph will be below the line where the point origin is not included.
Hence the graph is given below.

Look who I recreated
Part A: What is the approximate y-intercept of the line of best fit and what does it represent? (5 points) Part B: Write the equation for the line of best fit in the slope-intercept form and use it to predict the number of matches that could be won after 13 months of practice. Show your work and include the points used to calculate the slope
Answer:
Well I can't do it if you don not show the graph :(
Step-by-step explanation:
Answer:
Let's actually find the line of best fit...
m=(nΣyx-ΣyΣx)/(nΣx^2-ΣxΣx)
m=(11*836-130*55)/(11*385-3025)
m=2046/1210
m=93/55
b=(Σy-93Σx/55)/n
b=(55Σy-93Σx)/(55n)
b=(7150-5115)/(55*11)
b=185/55, so the line of best fit is:
y=(93x+185)/55
A) The approximate y-intercept (the value of y when x=0) is 185/55≈3.36.
Which means that those who do not practice at all will win about 3.36 times
B) y(13)=(93x+185)/55
y(13)≈25.34
So after 13 months of practice one would expect to win about 25.34 times.

Answer:
The answer should be 77, but the triangle in the question seems off. Read the explanation.
Step-by-step explanation:
To find the exterior angle in this problem, you can use the exterior angle theorem.
Interior angle + interior angle = exterior angle
25 + 52 = 77
You can double-check this answer by figuring out the third interior angle.
Since the sum of all the interior angles of a triangle should be 180, you can determine that
25 + 52 + y =180
Y= 103
or, since a straight line is always 180 degrees (Y+X=180)
25+52+(180-x)=180
X= 77
The reason why I think the question looks weird is since 77 is an acute angle, and even though it's the only answer that makes sense in this question, angle X is clearly an obtuse angle, as shown in the picture.

Why do equivalent ratios form a straight line when graphed?
The vertical distance between points is constant, and the horizontal distance between points increases with each point.
The ratio of the change in y-values to the change in x-values is equivalent for any two points in a graph of equivalent ratios.
The horizontal distance between points is constant, and the vertical distance between points increases with each point.
The y-values of equivalent ratios increase at a constant rate, and the x-values decrease at a constant rate.
Answer:
D-The y-values of equivalent ratios increase at a constant rate, and the x-values decrease at a constant rate.

No. Since 7^2+9^2=11^2, the triangle cannot be a right triangle.
9514 1404 393
Answer:
No. Since 7^2 + 9^2 ≠ 11^2, the triangle cannot be a right triangle.
Step-by-step explanation:
You may recall that side lengths of 3, 4, 5 make a right triangle. That particular triple has several interesting characteristics. One is that it is the only (reduced) triple that is an arithmetic sequence (has a constant difference between the side lengths). Any right triangle that has sides that differ by a constant amount must be a multiple of 3, 4, 5.
Here, we have sides of length 7, 9, 11—values that differ by 2. They form an arithmetic sequence that is not a multiple of 3, 4, 5, so we know right away they cannot be sides of a right triangle.
__
If we want to use the Pythagorean relation to check, we can see if the equation is true:
7² + 9² = 11²
49 + 81 = 121
130 = 121 . . . . . . Not True
