Answer:
Step-by-step 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
its d
y - x = -5
y = x-5
y = 2x² - 3x - 5
x-5 = 2x² - 3x - 5
2x² - 4x = 0
x² - 2x = 0
x(x - 2) = 0
x = 2, 0
(x,y) = (2,-3), (0,-5)
