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?

m = yx + b
m = y-b/x
m =y/x-b
m = y – b/x

Answer 1

y = mx + b....subtract b from both sides
y - b = mx ....divide both sides by x
(y - b) / x = m

Answer 2

Option b

Explanation:

GIven is an equation of a straight line in slope intercept form

y = mx+b

where m=slope, b = y intercept and (x,y) ordered pair on the line

We are to solve for m

y =mx+b

Revert left side and right side

`mx+b=y`

Subtract b from both sides

`mx=y-b`

Divide by m

`m=(y-b)/(x)`

Thus we find that option b is right answer
