Chapter 1: Q. 42 (page 41)

Find an equation of the line L.

Short Answer

Expert verified

The equation of line isy=-x+3

Step by step solution

01

Step 1. Given Information

The given graph is

02

Step 2. Explanation 

From the given figure, we know the line is parallel to line y=-x

On comparing with the equation of line, we get the slope of line as -1and as lines are parallel so the slope of the other line will also be-1.

Substitute the values in the general form of equation of slope- line format.

y-y1=m(x-x1)y-2=-1(x-1)y-2=-x+1y=-x+3
