$y = 4 x + 4$ , $y = 6 x$

Step 1

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

Step 1.1

The slope-intercept form is $y = m x + b$ , where $m$ is the slope and $b$ is the y-intercept.

$y = m x + b$

Step 1.2

Find the values of $m$ and $b$ using the form $y = m x + b$ .

$m_{1} = 4$

$b = 4$

$m_{1} = 4$

$b = 4$

Step 2

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

Step 2.1

The slope-intercept form is $y = m x + b$ , where $m$ is the slope and $b$ is the y-intercept.

$y = m x + b$

Step 2.2

Find the values of $m$ and $b$ using the form $y = m x + b$ .

$m_{2} = 6$

$b = 0$

$m_{2} = 6$

$b = 0$

Step 3

Compare the slopes $m$ of the two equations.

$m_{1} = 4, m_{2} = 6$

Step 4

Compare the two slopes in the decimal form. If the slopes are equal, then the lines are parallel. If the slopes are not equal, then the lines are not parallel.

$m_{1} = 4, m_{2} = 6$

Step 5

The equations are not parallel because the slopes of the two lines are not equal.

Not Parallel
