Chapter 4: Q. 420 (page 539)

Find the equation of a line with given slope and containing the given point. Write the equation in slope鈥搃ntercept form.

Horizontallinecontaining(-2,-3)

Short Answer

Expert verified

Equation of the line is y=-3.

Step by step solution

01

Step 1. Given information 

We have been given:

Horizontallinecontaining(-2,-3)

We have to write the equation in slope鈥搃ntercept form.

02

Step 2. Use the equation of the point-slope form of the line

The point-slope formula is y-y1=m(x-x1).

y-(-3)=0(x-(-2)) Slope of a horizontal line is zero.

03

Step 3. Write in slope-intercept form y=mx+b.

y-(-3)=0(x-(-2))y+3=0y=-3
