X = 3 * 40 / 15 = 8
The answer is 8
Answer: 2 is the y intercept
Step-by-step explanation:
Slope is rise over run and in this problem our y intercept is 2 because it is defined as the y. Negate your 9 and put it over the y intercept to make into a fraction to represent slope. This makes it y = mx + b form now.
y = - 9/2x + 2
Try A. Work it out. What do you think? Note that (-)(-) = (+).
