Find the midpoint,
(8,-6), (-4,4)
0 12, -1)
O (-16, 14)
O (1, 0)
O 16-5)

i used to know how to do this in 7th but i forget easily

step-by-step explanation:

the first one, all those points on the line just make a strait line.

  the correct choice is marked

step-by-step explanation:

the first two graphs show multiple turning points. the last graphs matches the description in every detail.

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
