To graph the point (4/5,0) find the point on the x-axis (the horizontal axis) that is 4/5 of a mark to the right of the origin.
To graph the point (0,-4) find the point on the y-axis (the vertical axis) that is 4 marks below the origin.
Draw the line that connect those two points.
To calculate the x-intercept, put 0 in for y: 0 = 5x - 4 --> 4 = 5x --> x = 4/5
To calculate the y-intercept, put 0 in for x: y = 5(0) - 4 --> y = -4
