Answer:
4
Step-by-step explanation:
Slope-intercept form is y = mx + b, and m is the slope
Because the slope is -3, m = -3
y = -3x + b
Plug in the point and solve for b
-7 = -3(-3) + b
-7 = 9 + b
-16 = b
a. y = -3x -16
Answer:
40
Step-by-step explanation:
the formula for area of a parallelogram is a = bh
you know area (a) = 160 and height (h) = 4, so:
160 = 4 * b
divide both sides of this equation by 4,
b = 40
the base is 40 meters long
