Two collinear points on a line are given in the table below: X y

0 0 (0,0)
2 1 (2,1)

Select the points that do not lie on the line.

(4,2)
(4, 3)
(7,2)
4/8, 2/8

and do not lie on the line

Step-by-step explanation:

Given

Required

Determine which points that are not on the line

First, we need to determine the slope (m) of the line:

Where

So;

Next, we determine the line equation using:

Where

becomes

To determine which point is on the line, we simply plug in the  values of x to in the equation check.

For

and

Substitute 4 for x and 2 for y in

This point is on the graph

For

and

Substitute 4 for x and 3 for y in

This point is not on the graph

For

and

Substitute 7 for x and 2 for y in

This point is not on the graph

and

Substitute for x and for y in

This point is on the graph

think the answer is 30 degrees. if not than it is 20 degrees. not 100% sure. let me know if it was right.
