Recall that the slope-intercept form of a linear equation is as follows:
where m is the slope, and (0,b) is the y-intercept.
Therefore:
(a) The y-intercept of the graph of the linear equation y=4x-1 is (0,-1).
(b) The y-intercept of the graph of the linear equation y=4x is (0,0).
(c) The y-intercept of the graph of the linear equation y=4x+4 is (0,4).
Answer:
First graph option: a.
Second graph option: b.
Third graph option: c.
