Question

20. Determine whether the given points are on the graph of y = 3x + 2.

Select all points that lie on the graph.
(2,0)

(2,8)

(3,9)

(5,17)

Answer 1

The points that were given are not on the graph of y=3x+2.

Explanation:

The slope is 3 and the y-intercept is 2 so on the graph you rise three times from the point (0,0) to (0,3) then you run twice to the right so your first plot would be (2,3). After following the same process the next three plots would be (4,6),(6,9),&(8,12). So those plots that were given are incorrect. Remember y=mx+b

Mx is your slope to rise with and b is your y-intercept to run with.

Rise/run. I just put the important stuff in bold.
