Precalculus Examples

y = 3 x - 4

$y = 3 x - 4$

Step 1

Use the slope-intercept form to find the slope.

Tap for more steps...

Step 1.1

The slope-intercept form is

y = m x + b

$y = m x + b$ , where

m

$m$ is the slope and

b

$b$ is the y-intercept.

y = m x + b

$y = m x + b$

Step 1.2

Using the slope-intercept form, the slope is

3

$3$ .

m = 3

$m = 3$

m = 3

$m = 3$

Step 2

All lines that are parallel to

y = 3 x - 4

$y = 3 x - 4$ have the same slope of

3

$3$ .

m_{parallel} = 3

$m_{parallel} = 3$
