Answer:
<u>Point-slope form</u>: y - 8 = -9/2(x + 4)
Step-by-step explanation:
Given points (-4, 8) and (-2, -1)
In order to determine the point-slope form of the line, we must first solve for its slope by using the following formula:
m = (y2 - y1)/(x2 - x1)
Let (x1, y1) = (-4, 8)
(x2, y2) = (-2, -1)
Substitute these values into the slope formula:
m = (y2 - y1)/(x2 - x1)
m = (-1 - 8)/ [-2 (-4)]
m = -9/(-2 + 4)
m = -9/2
Therefore, the slope is m = -9/2.
Next, using the slope, m = -9/2, and one of the given points, (-4, 8), substitute these values into the point-slope form:
y - y1 = m(x - x1)
y - 8 = -9/2[x - (-4)]
y - 8 = -9/2(x + 4)

Answer:
4
Step-by-step explanation:
yeah yeah yeah yeah 2+2=4
This question is essentially asking you to find the surface area of the box.
The formula for SA on a rectangular prism is: 2(L*W+L*H+W*H)
L=Length W=Width H=Height
Lets input the information we know:
2(20*8+20*30+8*30)
Follow BEDMAS
2(160+600+240)
2(760+240)
2(1000)
2*1000
=2000
The box will need 2000 centimeters squared of material.
Hope this helps!
