Chapter 3.5, Problem 49SPR

To determine

To write in slope intercept form for the line that having slope and y-intercept.

$m:\frac{4}{5}$ , $(0,-9)$

Answer to Problem 49SPR

Slope intercept form

  $y=\frac{4}{5}x-9$

Explanation of Solution

Given information:

Slope

  $m:\frac{4}{5}$

Y-intercept

  $(0,-9)$

Formula used:

Slope intercept form

  $y=mx+b$

Calculation:

The line having slope and y-intercept

  $m=\frac{4}{5}$

  $(0,0.5)$

The general slope intercept form is given as

  $y=mx+b$

Where

  $m$ is slope

  $b$ is y-intercept

Then

  $b=-9$

Substitute value of slope and y-intercept in general slope intercept form

  $y=\frac{4}{5}x+(-9)$

On simplify

  $y=\frac{4}{5}x-9$

Hence, slope intercept form is $y=\frac{4}{5}x-9$ .
