We make a right-angled triangle: And then use Pythagoras:. This is slope intercept form, y = 3x - 6. two x-intercepts, one x-intercept or no x-intercepts found when the graphs of the quadratic functions are drawn. For the equation, "y = mx + b", m is the slope of the line that is multiplied by x and b is the y-intercept or we can say the point where the line will cross the vertical y-axis. This is a sensible equation that can also be named as the slope-intercept form. x-intercept (s): x-intercept (s): Step 2. So, the x-intercept of the line y=2x4 is 2. The center C is a point on the perpendicular bisector of the two y intercepts that is the line y = 13, so C = ( , 13).
