Question

Help pleaseeeee :( find slope and y-intercept 6x+3y= -9

Answer 1

The slope-intercept form of the equation of a line is

y = mx + b

where m = slope, and b is the y-intercept.

Solve your equation for y.

6x + 3y = -9

3y = -6x - 9

y = -2x - 3

Now compare this equation with

y = mx + b

m = slope = -2, and b = -3

The slope is -2, and the y-intercept is -3.
