Chapter 13.7, Problem 11CE

To determine

To state : the slope of the line and name two points on the line

Answer to Problem 11CE

The slope of the line is $-1$ and the two points are $\left(0,-7\right)$ , $\left(1,-8\right)$

Explanation of Solution

Given information :

  $y=-\left(x+7\right)$

Formula used :

  $y=mx+b$

Calculation :

Let the slope of the line $=m$

The equation is $y=-x-7$

Therefore, the slope of the line $=-1=m$

Let the point $x=0$

Therefore, the equation is $y=-7$

Let the point $x=1$

Therefore, the equation is $y=-1-7=-8$

Therefore, the first and second point are $\left(0,-7\right)$ and $\left(1,-8\right)$

Hence, the slope of the line is $-1$ and the two points are $\left(0,-7\right)$ , $\left(1,-8\right)$
