The slope is 3, the y-intercept is 0, and the x-intercept is 0.


This equation is in slope-intercept form (y = mx + b), so the slope, m, is 3. The y-intercept, b, is an understood 0 in this case as there is no constant term added to the x-term. To find the x-intercept, substitute 0 for y in the equation and solve for x:
0 = 3x
0/3 = 3x/3
O = x
