An equation in slope intercept form is:

Substitute values for m and b

Actual area = 42ft²
The actual area will simply be calculated as:
= 6 × 7
= 42 feet²
Answer:
y = -7.2x + 540
Step-by-step explanation:
to find the slope I used the x-and-y intercepts: (0, 540) and (75, 0)
slope = 540/-75 or -7.2
You need to subtract 25 by 18
