Respuesta :

Slope intercept: y = mx + b
Subtract 9x from both sides
15y = -9x + 45
Divide by 15
Solution: y = -9/15x + 3

Answer:

y= - 3/5 x+3

Step-by-step explanation:

-\frac{3}{5}x+3:\quad -\frac{5x-15}{3}

I know that looks like it makes no sence but im pretty sure your answer is

y= - 3/5 x+3  or m= - 3/5
