Chapter 3: Q. 191 (page 293)

Determine an equation of the line that contains the points (7,2) and (7,-2). Write the equation in slope-intercept form.

Short Answer

Expert verified

The equation in slope-intercept form isy=-4x+26

Step by step solution

01

Given information. 

The given point is (7,2) and (7,-2).

02

Determine the slope by using the given points. 

The slope should be calculated by applying the following formula

m=y2-y1x2-x1m=-2-(2)7-7m=-40m=-4

03

Select one point

Select either point

x1=7,y1=-2

04

Simplify the equation in point-slope form y-y1=m(x-x1) 

y-y1=m(x-x1)y-(-2)=-4(x-7)y+2=-4x+28y=-4x+28-2y=-4x+26
