Question 154496: Find the value of b so that the graph of bx+5y=8 and has a slope of 4. Found 2 solutions by BrittanyM, kevwill:Answer by BrittanyM(80) (Show Source):
But with a little bit of work, we can put this into the same form and begin solving for b.
bx + 5y = 8
5y = -bx + 8
Now that it's in a familiar form, we can begin solving for b. For the line equation model, we know that the slope is m, which in our equation is , so we just have to ask ourselves, "What number divided by five equals four?"
You can put this solution on YOUR website! The original solver started out right, but got a little careless with her signs.
Given that we need to find b such that the slope is 4, we have
So the correct answer is b = -20, not b=20 as stated by the original solver.
