Avg difficulty 2.5

After graphing it, use the 2nd CALC button and 1:value button, hit enter. At the lower part of the screen you will see “x=” and a blinking cursor. You may enter any number for x and it will display the y value for any x value you input. Use this and plug in x = 0, thus finding the y-intercept, for each of the following graphs.

Y 1 = 3x−8 4 \text{Y}_{1} = \frac{3 x - 8}{4}
