Answer explanation

To graph a line, start with the y-intercept and then use the slope to create the line.

Here the y-intercept is (0, 4). And the slope is -2/3, which takes us down 2 then right 3 (or up 2 then left 3). We can check to see if we used slope correctly depending on how the line reads. Since the slope is negative, our line should be decreasing.
