Question

A line passes through the point (-2, 1) and has a slope of 3. Write an equation in slope-intercept form for this line. ​

Answer 1

y = 3x + 7

Explanation:

apply the rule

`y-y_(0) =m(x-x_(0) )`

where

`x_(0), y_(0)`

they are taken from the point (-2, 1), and "m" is the slope (3)

Then

`y-1=3(x--2)`

`y-1=3(x+2)`

`y=3x+6+1`

`y=3x+7`

Hope this helps
