Question

find the slope and y intercept of the equation
4x + 5y = -9

Answer 1

If you convert it to slope-intercept form, you will be able to read the answer right from the new form.

Slope-intercept form means we need to get from Ax + By = C to y = mx +b

To do this, start with your equation 4x + 5y = -9

Answer 2

Thanks, @Mehek14 ! Of course, @brunerc1141 has "left the building".
I'm going home for the night also.

No one is moving very fast on this problem.

Answer 3

express in intercept form
(x/A) + (y/B) = 1
given 4x + 5y = -9

so
(4x/-9) + (5y/-9) = 1
(x/(-9/4)) + (y/(-9/5)) = 1

So intercept => A = -9/4, B=-9/5
So coordinates are (A, 0) and (0,B)
Slope = (0-B)/(A-0) = -B/A

put the values and solve them
