Answer:
b) m = -2 and b=10 and c) m= 2/5 and b=4
Step-by-step explanation:
For b, we know that the b value (y-intercept) is 10 because it is the y value when x= 0, which is shown on the table as 10.
Next, to find the slope (m-value) we know that 10 gets added to the y value so then x(2) + 10 = 6
subtract 10 from both sides and you get 2x = -4
divide both sides by 2 to get x= -2 or our m-value (slope)
-------------------------------------------------------------------------------------------------------------
For c, we know that the graph intercepts the y-axis at 4, so that is our b value.
We know know: y= m(x) + 4
To find the slope, we use the formula: rise/run
When the graph goes up 6 to get to y=10, the x value goes 15 across
Rise = 6 ; Run = 15
6/15 = 2/5
Therefore, the m value is 2/5

The size of the cardboard piece required is 7627.0 in.
The formula for finding the size of a box is
2(L + W) + 8L + 8W = Perimeter of the cardboard piece
Where L = Length, W = Width
We need to find L and W to find the size of the cardboard piece.
7623 = 2(L + W) + 8L + 8W
7623 = 2L + 2W + 8L + 8W
7623 = 10L + 10W
7623/10 = L + W
762.3 = L + W
Let's take L = 500 and W = 262.3 (762.3 - 500 = 262.3)
Now we plug in the values of L and W in the original formula
2(500 + 262.3) + 8(500) + 8(262.3) = 7623
2(762.3) + 4000 + 2102.4 = 7623
1524.6 + 4000 + 2102.4 = 7623

24 children x $4/child = $96
Similarly, we can find the total cost of the adult tickets:
Adult tickets cost = Number of adult tickets x Cost per adult ticket
In this case, the number of adult tickets is 2 adults/family x 6 families = 12 adults
The cost per adult ticket is $8.
So, the total cost of the adult tickets would be:
12 adults x $8/adult = $96
To find the total cost of the festival tickets, we can add the cost of the child tickets and the cost of the adult tickets:
Total cost = Child tickets cost + Adult tickets cost
$96 + $96 = $192
So, the total cost of the festival tickets for 6 families with 2 adults and 4 children would be $192.

Where is (-4,-2.5) in the easiest way to put it
(-4, -2.5) represents a point on the cartesian coordinate system having -4 units on the x axis and -2.5 units on the y axis
What is cartesian coordinate system?A Cartesian coordinate system in a plane is a system of coordinates that identifies each point uniquely by a pair of numerical coordinates, which are the signed distances to the point from two fixed perpendicular oriented lines, measured in the same unit of length.
The two fixed perpendicular oriented lines are
x axisy axisThey are represented by a pair of numerical coordinates called ordered pair. The ordered pair are arranged such that the x values are first then a comma and the y values.
This is written as (x, y) hence for (-4, -2.5) x = -4 and y = -2.5
