Question

A line passes through the points (3, –3) and (18, –3). What is its equation in slope-intercept form?

Answer 1

Answer: y=-3

Explanation:

slope intercept form:y=mx+b

m= slope

b= y-intercept

use the slope formula to get the slope

y2-y1/x2-x1

-3-(-3)/18-3

0/15

0

y=0x+b

plug in values from (3,-3) and solve for b

-3=0(3)+b

-3=b

y=-3
