Question

The slope intercept form of the equation of a line is y=mx+b. when the formula is solved for m, the result is?

a. y-x/b
b. y-bx
c. y-b/x
d. x/y - b

Answer 1

`\displaystyle\\Answer:\ c.\ (y-b)/(x)`

Explanation:

Given: y=mx+b

y-b=mx+b-b

y-b=mx

Divide both parts of the equation by x:

`\displaystyle\\(y-b)/(x)=m\\ Thus,\ m=(y-b)/(x)`
