<prompt> Find the x-intercept of the equation y 2x 4.  <response>: The x-intercept of a line is the point at which the line intersects the x-axis. At this point, the y-value is always zero. We can use this information to find the x-intercept of the line represented by the equation y 2x 4.To find the x-intercept, we need to substitute y 0 into the equation and solve for x.0 2x 4-4 2xx -2Hence the x-intercept of the line represented by the equation y 2x 4 is -2, 0.
