What is m ZABC?
OM ZABC = 15°
OM ZABC = 45°
om ZABC = 60°
m ZABC = 75°

26

step-by-step explanation:

the function makes a strait line horizontally with no x intercept but a y intercept at 9.

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
