You can put this solution on YOUR website!
The y-intercept is the value of y at the point where the line crosses the y axis(x=0).
The x-intercept is the value of x at the point where the line crosses the x axis(y=0). If we set x=0, we get y=0.
So the x intercept and the y intercept are the same value of 0.
You know the line goes through the origin (0,0).
Pick another value for x and find the y and then you'll have two points on the line.
For example, for x=1, y=4x=4(1)=4 and (1,4) is another point on the line.
