Answer:
4/3
Step-by-step explanation:
12x-9y=-9
9y=12x-(-9)
9y=12x+9
y=12/9x+9/9
y=4/3x+1
y=mx+b where m=slope and b=y-intercept,
so the slope is 4/3
Answer:
rate of change = -0.32
Step-by-step explanation:
Rate of change = slope,m

First you solve 2y-3y=9.

Now that you have y, then you substitute y into x-2y=3 to find X

Your solution is (-15, -9)
