Question

The slope-intercept form of a linear equation is y = mx + b, where x and y are coordinates of an ordered pair, m is the slope of the line, and b is where the line crosses the y-axis.
Which is an equivalent equation solved for the slope, m?

a. m = yx + b
b. m =
c. m = – b
d. m = y –

Answer 1

y=mx+b

subtract b over so that

y-b=mx

then divide by x so the answer is

m=(y-b)/x

Answer 2

Divide both sides by x + b to get m by itself. The equation will look like this: m = $\frac{y}{x+b}$
