Question

anyone know how to this one :(
Find the intercepts, and then graph the line.
-3x-9y=9

Answer 1

Simplify the equation and solve for y.
-3x-9y=9
-9y=-3x+9
y=3/9x-9/9
y=1/3x-1

The equation of the line is now in slope intercept form and y=1/3x-1.

Answer 3

The slope is rise over run, and in this case our slope equals 1/3, so the line travels up 1 and over 3. The y-intercept is (0, -1).

When you graph the line, start at (0, -1) and go up 1 and over 3 and make a point. Keep doing this, then connect them with a straight line.
