Answer:
y = -1/8x + 35/8
Explanation:
First, find the slope by subtracting 5 by 4 and -5 by 3. 5-4=1 and -5-3 equals -8. So, the slope is 1/-8. This is your current equation: y = -1/8x + b. Plug in one of your points to the equation, it doesn't matter which one. I'm going to use the second point, so it should look like this: 4 = -1/8(3) + b. -1/8 times 3 equals -3/8. So, this is what you should have: 4 = -3/8 + b. Add 3/8 to both sides of the equation to get 35/8 = b. Go back to your original equation and plug 35/8 in for b. This is your final equation: y = -1/8x + 35/8. Hope this helped!
