Answer:
m=3
Step-by-step explanation:
The equation of the line is in slope-intercept form, or:
y=mx+b
where m is the slope and b is the y-intercept. The slope is multiplied by x and the y-intercept is added or subtracted from that.
The equation of the line is:
y=3x+7
3 and x are being multiplied, therefore 3 is the slope. 7 is added to 3x, therefore 7 is the y-intercept.
The slope is 3, or 3/1. Therefore, on a graph, the line will rise 3 up, then run 1 to the right.
The slope of the line is 3.
