find the slope and the y intercept of the line. Please help me I keep getting the y intercept wrong.

8x=9y + 54
I got the slope correct but I cant get the y intercept.

• math -

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.

• math -

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)
