Answer:
Equation: y = 3x + 9
Step-by-step explanation:
To find equation:
Take two coordinates: ( 1 , 12 ) , ( 2 , 15 )
Secondly find slope: ( y2 - y1 ) / (x2 - x1 )
Using the formula: ( 15 - 12 ) / ( 2 - 1 )
: 3 ............this is our slope, m
Using formula to find equation: y - y1 = m ( x - x1 )
: y - 12 = 3 ( x - 1 )
: y = 3x - 3 + 12
: y = 3x + 9 .....our final answer.
The equation in slope intercept form is y = 3x + 9
