Chapter 4: Q. 421 (page 539)

Find the equation of a line with given slope and containing the given point. Write the equation in slope–intercept form.
$Horizontal line containing (- 1, - 7)$

Short Answer

Expert verified

Equation of the line is $y = - 7$ .

Step by step solution

Step 1. Given information

We have been given:

$Horizontal line containing (- 1, - 7)$

We have to write the equation in slope–intercept form.

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

The point-slope formula is $y - y_{1} = m (x - x_{1})$ .

role="math" localid="1647333672443" $y - (- 7) = 0 (x - (- 1))$ Slope of a horizontal line is zero.

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

$y - (- 7) = 0 (x - (- 1)) y + 7 = 0 y = - 7$
