3.) A 50ft by 40ft one-story house sits in the middle of a lot that is 80 ft by 60ft. If the edge of the house to the
edge of the lot is covered in grass, how many square feet
of grass will the owner mow?

2800 ft^2

Step-by-step explanation:

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
