Question

Which is the equation if the line with a slope 3 that contains points -1,5

Answer 1

y = 3x + 8

Slope = m
m= 3

y = mx + b

Answer 2

y- 5 = 3(x+1) point slope form

y = 3x+8 slope intercept form

Explanation:

using point slope form of a line

y-y1 = m (x-x1)

y-5 = 3 (x--1)

y- 5 = 3(x+1)

if we want slope intercept form of the line

distribute

y-5 = 3x+3

add 5 to each side

y-5+5 = 3x+3+5

y = 3x+8
