Chapter 8.7, Problem 13PPS

To determine

To calculate: To state the slope and the y-intercept of the graph of equation

Answer to Problem 13PPS

Slope is $-9$ and y-intercept is $0$

Explanation of Solution

Given information: Equation is $y=-9x$

Formula Used:

Slope intercept form of line is $y=mx+c$ , where

  $m=$ Slope of graph of equation

  $c=$ y-intercept of graph of equation

Calculation:

Equation is given as

  $y=-9x$

Comparing the above equation to slope intercept form of line $y=mx+c$ ,

  $\begin{array}{l}m=-9\\ c=0\end{array}$

Hence, slope is $-9$ and y-intercept is $0$
