On the y-axis, x=0.
Take the equation you have, set x=0, solve what's left for 'y'. That's the y-intercept.

to find the y-intercept you plug in your x and y values in to the equation of y=mx+b. b is the y intercept and m is the slope. To find the x-intercept, set y = 0, and find value of x that satisfies the equation. If it is a line in the form y=mx+b, then the x-intercept will be at x= -b/m
y = {slope}x + {y intercept}
Use the equation; y=mx+b where m is the slope Use your 2 points as y and b (intercept)
The y-intercept is whatever number (with no variable) is added onto the end of the equation y=mx+b. In this case b is the y-intercept. In y=15x the y-intercept is 0 because there is no number without a variable on the end.
