Find the Slope and y-intercept y=5(9x+80)

$y = 5 (9 x + 80)$

Step 1

Rewrite in slope-intercept form.

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

$y = m x + b$

Simplify the right side.

Simplify $5 (9 x + 80)$ .

Apply the distributive property.

$y = 5 (9 x) + 5 \cdot 80$

Multiply.

Multiply $9$ by $5$ .

$y = 45 x + 5 \cdot 80$

Multiply $5$ by $80$ .

$y = 45 x + 400$

Step 2

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

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

$m = 45$

$b = 400$

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

Slope: $45$

y-intercept: $(0, 400)$

Slope: $45$

y-intercept: $(0, 400)$
