HEL For g(x) = -2x, find g(x) when x = 4 and when x=-1.

For h(x) = 3x – 1, find h(x) when x = -2 and when x = 7

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
