Pre-Algebra Examples

h (x) = 2

$h (x) = 2$

Step 1

Rewrite the function as an equation.

y = 2

$y = 2$

Step 2

Use the slope-intercept form to find the slope and y-intercept.

Step 2.1

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 2.2

Find the values of

m

$m$ and

b

$b$ using the form

y = m x + b

$y = m x + b$ .

m = 0

$m = 0$

b = 2

$b = 2$

Step 2.3

The slope of the line is the value of

m

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

b

$b$ .

Slope:

0

$0$

y-intercept:

(0, 2)

$(0, 2)$

Slope:

0

$0$

y-intercept:

(0, 2)

$(0, 2)$

Step 3

Find two points on the line.

\begin{array}{c} x & y \\ 0 & 2 \\ 1 & 2 \end{array}

$\begin{array}{c} x & y \\ 0 & 2 \\ 1 & 2 \end{array}$

Step 4

Graph the line using the slope, y-intercept, and two points.

Slope:

0

$0$

y-intercept:

(0, 2)

$(0, 2)$

\begin{array}{c} x & y \\ 0 & 2 \\ 1 & 2 \end{array}

$\begin{array}{c} x & y \\ 0 & 2 \\ 1 & 2 \end{array}$

Step 5

h (x) = 2

$h (x) = 2$
