Question

Find the slope and y-intercept for the graph of the equation: 9x - 3y = 81

Answer 1

y = -3x - 27

Explanation:

9x - 3y = 81

-3y = 9x + 81

-3y/3 = 9x/3 + 81/3

-y = 3x + 27

y = -3x - 27

Answer 2

the slope of the graph is 3 and the y-intercept is -27. This means that the graph crosses the y-axis at the point (0,-27).
