Answer:
You plug x into the equation and then you can solve for y.
Explanation:
For example: if the equation was y = 2x + 2
Plug in x=0 and you get y = 2*0+2; y = 2
Therefore, the y intercept is (0,2)
The y-intercept is the point at which the graph crosses the y-axis. At this point, the x-coordinate is zero. To determine the x-intercept, we set y equal to zero and solve for x. Similarly, to determine the y-intercept, we set x equal to zero and solve for y.
