Question

What's the equation of the line that passes through the points (-8,4) and (0,22)?

A) y= -9/4x+22
B) y=4/9x+22
C) y=9/4x
D) y=9/4x+22

Answer 1

its d

Explanation:

Answer 2

Explanation:

y=mx+b where m=slope and b=y intercept

m=(y2-y1)/(x2-x1)=(22-4)/(0+8)=2.25

y=2.25x+b, using point (0,22) we can solve for b

22=2.25(0)+b

b=22

y=2.25x+22 or stating it fractionally

y=9x/4+22
