Do the points (2, 5), (4, 3.5), and (7, 1.5) lie on the same line? How do you know? Prove your answer.

i use my brain for prombles like this maybe you could try it

step-by-step explanation:

hi! i think the answer is 1/2 : )

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
