I sketched the graph and indicated the x intercept with a blue dot and the y intercept with a red dot. I am going to find the y intercept first. Do do this I want the coordinates of the point where the line crosses the yaxis. If a point is on the yaxis then its xcoordinate is zero so set x = 0 in the equation and solve for y.
Hence the point where the line crosses the yaxis is (x, 2). The y intercept is the ycoordinate of this point so
Now that we have done it once we can find the x intercept much quicker. To find the x intercept set y = 0 and solve for x
and hence
Now try the two equations in your question to us and write back if you need more assistance,
