Question

Find an equation of the line passing through the pair of points. Write the equation in slope-intercept form.

(3,7), and (7.3)
y=0

Answer 1

y=10-x

Explanation:

1. Find the slope of the equation using the formula (change in y/change in x)

(3-7)/(7-3)=-4/4=-1

2. Plug in the slope and one of the coordinate points to the slope-intercept form to find the y-intercept.

slope-intercept form: y=mx+b

7=-3+b

b=10

3. Put the slope-intercept form of the equation together.

y=10-x
