$- 3 x + y = 5$

Step 1

Rewrite in slope-intercept form.

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

Add $3 x$ to both sides of the equation.

$y = 5 + 3 x$

Step 1.3

Reorder $5$ and $3 x$ .

$y = 3 x + 5$

Step 2

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

Step 2.1

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

$m = 3$

$b = 5$

Step 2.2

The slope of the line is the value of $m$ , and the y-intercept is the value of $b$ .

Slope: $3$

y-intercept: $(0, 5)$

Slope: $3$

y-intercept: $(0, 5)$
