You will need to substitute 0 for y and solve.
C
Think of the point where the graph of an equation intercepts the x-axis. The y-coordinate of this point is 0. Therefore, to find the x-intercept of a line, we need to substitute 0 for y in its equation.
An x-intercept of 4 means that the graph passes through the x-axis at the point ( 4,0). This result corresponds with choice C.
