Answer:

-4/5 is the slope and -9/5 is the y intercept

Explanation:

4x+5y = -9

Subtract 4x from each side

4x-4x+5y =-4x -9

5y = -4x -9

Divide by 5

5y/5 = -4x/5 -9/5

y = -4/5 x -9/5

This is in slope intercept form y = mx+b where m is the slope and b is the y intercept

-4/5 is the slope and -9/5 is the y intercept
