Precalculus Examples

f (x) = 4 x + 2

$f (x) = 4 x + 2$

Step 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 2

Find the values of

m

$m$ and

b

$b$ using the form

y = m x + b

$y = m x + b$ .

m = 4

$m = 4$

b = 2

$b = 2$

Step 3

The slope of the line is the value of

m

$m$ , and the y-intercept is the value of

b

$b$ .

Slope:

4

$4$

y-intercept:

(0, 2)

$(0, 2)$
