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 = m = – b m = y –

Answer 1

y = mx + b
y - b = mx
(y - b) / x = m

so its : m = (y - b) / x.....or m = (y/x) - (b/x)

Answer 2

we know that

The slope-intercept form of a linear equation is

`y=mx+b`

where

m is the slope

b is where the line crosses the y-axis

Solve the equation for the slope

`y=mx+b`

Subtract
`b` both sides

`y-b=mx+b-b`

`y-b=mx`

Divide by
`x` both sides

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

`m=(y-b)/x`

therefore

the answer is

`m=(y-b)/x`
