Answer:
The slope is 3/2
Step-by-step explanation:
The slope is a in the equation y= ax +b
The equation is -8y = -12x +9 -7 → -8y = -12x +2
When we make this possitive by multiplying by -1 the equation will be
8y= 12x -2
To get Y we have to divide by 8
y= 12/8 x - 2/8
The slope is 12/8 or if we simplify it 3/2
