Marcus plotted the points (0, 0), (6, 2), (18, 6) and (21, 7) on a graph. he wrote an equation for the relationship. find another ordered pair that could be a solution of marcus’s equitation. justify your answeryou for answering if you do, !

From the point (0, 0), we know that the y-intercept is 0.
If we use the slope formula on the first two points:

we get 1/3 as the slope.
Therefore, our equation in slope-intercept form is:

To find a point, we can plug in any x and solve for y, let's use x=1

Therefore, our point is (12, 4)
