8x = 9y + 54.

Put Eq in STD Form:

8x - 9y = 54

The y-Int IS the point where the graph crosses the y-axis and x = 0. Therefore, you should substitute 0 for

x in your STD Eq and solve for y.

8 * 0 - 9y = 54

y = -6 = y-Int.

P(0 , -6).

Slope = -A/B = -8/-9 = 8/9.

Determine the x-intercept and y-intercept of 3x - 6y = 12.(Points : 2)

(9, 0) and (0, -3)

(4, 0) and (0, -2)

(-4, 0) and (0, 4)
