Answer:

Solve the given equation for y to obtain the slope and y-intercept of this equation: -3x + 9y = 18

Add 3x to both sides: 3x - 3x + 9y = 18 + 3x

Simplifying, 9y = 3x + 18

Dividing both sides by 9 to solve for y:

y = (3/9)x + 2 or (after reduction) y = (1/3)x + 2

The slope is 1/3 and the y-int. is (0,2).

Y= -1/3x+2 because The Change in x and the change in y come out to -1/3x then you plug in the coordinates and solve for b. Hope i helped
