Slope: $-2/3$

Y-intercept: $3$

Solve for y. Add 2x on both sides:

$-2x-3y+2x=9+2x$

$-3y=9+2x$

Divide by -3 to everything:

$-3y/-3= 9/-3 + 2x/-3$

$y=(-2/3)x+3$

Now it's in the form $y=mx+b$ where m is the slope and b is the y-intercept.

Slope: $-2/3$

Y-intercept: $3$

How do you find the slope and intercept of –2x – 3y = 9–2x – 3y = 9?
