Work Step by Step

Only equations with a slope that is not 0 have an x-intercept. For instance, the equation y=3 will always have a y value of 3. Since y will never be 0, there is no x-intercept. However, this equation is a straight line, so it clearly is possible to have a linear equation with no x-intercept.
