Answer:
It's C, pretty simple
Step-by-step explanation:
Answer:
Width = 12
Length = 58
Step-by-step explanation:
Width = x
Length = 4x + 10
Perimeter = 140
2 * ( length + width ) = 140
2 * (4x +10 + x) = 140
5x + 10 = 140/2 = 70
5x = 70- 10
5x = 60
x = 60/5 = 12
Width = 12
Length = 4 * 12 + 10 = 48 +10 = 58
The y-intercept is where the graph goes through the y-axis (the vertical line in the center). It goes through at y=-9, so the coordinates would be (0,-9), since it is (x,y).
