Chapter 4: Q. 126 (page 530)

Find an equation of a line containing the points(-4,-3)and(1,-5).

Short Answer

Expert verified

The equation of the line isy=-25x-235.

Step by step solution

01

Step 1. Given Information.

The points are:

(-4,-3)and(1,-5).

02

Step 2. Finding the Slope.

The slope of the line is,

m=y2-y1x2-x1

Inputting the values,

role="math" localid="1647329823798" m=-5-(-3)1-(-4)

=-5+31+4=-25

03

Step 3. Equation of a line.

The point-slope form is,

(y-y1)=m(x-x1)

Inputting the values,

(y-(-3))=-25(x-(-4))y+3=-25(x+4)y+3=-25x-85y=-25x-235
