Question

what is the slope of these two equations.
4x+5y=15
16x+20y=0

Answer 1

the easiest way is to change the equations to slope intercept form whcih is]
y=mx+b where m=slope
i'll do the first one

4x+5y=15
-4x -4x
--------------
5y=-4x+15 divide both sides by 5

y=-4/5x +3
so now its in y=mx+b form
and your m=-4/5
so your slope is -4/5

can you try to do the other one?

Answer 2

-4/5 qagain
