Good idea. Let's take the same example I used to answer a different question. Look for the points where the graph cross the x- and y-axes.

In this graph, A is the point where the graph crosses the y-axis and B is the point where the graph cross the x-axis.

The y-intercept of the line is the y-coordinate of point A which is 1.

The x-intercept of the line is the x-coordinate of point B which is 1.5.

To find X-intercept for a linear equation put y=0 and solve for x.

To find Y-intercept put x=0 in equation and solve for y.

here the X-intercept is (x,0) and Y-intercept is (0,y)

you can get clear idea on intercepts by seeing above graph

For x-intercept put y=0 in equation, so you get (3,0)

For y-intercept put x=0 in equation, so you get (0,-2)

where the line intersects the y-axis, it is the y-intercept. Where it intersects the x-axis, is what the x-intercept is.
