Answer:

equation: y = 3x + 9

Step-by-step explanation:

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

find slope: [tex]\frac{y2-y1}{x2-x1}[/tex]

                :  [tex]\frac{15-12}{2-1}[/tex]

               :      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
