174. Finally the calculator gives us the point at which the line crosses the x-axis. Theexact values that cross the x-axis. This line crosses the x-axis at point (-5, 0).1. First graph the equation:Find the y-intercept of y = x + 52. Press [2 nd ] then press [CALC] and select Value:3. Enter into “0” into the X= (because where the line crosses the y axis the value forx is zero. Then press [enter]. This point is where the line crosses the y-axis,which is (0, 5). This is the y-intercept point.
