The bills offensive line let them down on 3 straight plays they lost ten yards. Twice the quarter was sacked. On the third play, they had a holding penalty. Write an expression using integers to represent the change in yardage. How many yards did the Bills lose?

its a straight line parallel to the time axis

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
