PLSSSS HELP I NEED THIS BY TOMORROW OR THE DAY AFTER PLS

Answer 1

equation: y = 3x + 9

Explanation:

first take two coordinates: ( 1 , 12 ) , ( 2 , 15 )

find slope:
`(y2-y1)/(x2-x1)`

:
`(15-12)/(2-1)`

: 3 ...........this is our slope, m

use the formula to solve or equation: y - y1 = m( x - x1 )

y - 12 = 3 ( x - 1 )

y = 3x - 3 + 12

y = 3x + 9
