Answer:
0
Step-by-step explanation:

Cross multiple:
9x=10x
Move them to one side
0=1x
Divide
0=x
Each ounce of yogurt costs $0.12 so 8 ounces would be $0.96
(0,6)(4,3)
slope = (3 - 6) / (4 - 0) = -3/4
ur y int (where the line crosses the y axis) is (0,6)
in y = mx + b form, the slope will be in the m position and the y int will be in the b position.
Therefore, ur equation is : y = -3/4x + 6 <==
Your answer for m would be -4, as -4x9=-36, and -36+36=0
