What is the equation of the line containing the points (5,2), (10,4), and (15, 6)?
O A. y= 1/5x + 1
O B. y = x-3
O C. y=2/5x

Will show energy on x axis time on the y axis feel free to ask any questions

So the first thing we do is to multiply the top equation by 3. the reason i want to do this is i notice there will be a 6y on both equations and can possibly add/subtract them. so we get 6y = -3x + 27. adding that and the second equation we get 6x = 27-15 which is 12. divide by 6 and we get 2. ∴ x = 2. substituting 2 into the first equation we get 2y = -2 + 9 which is 7. divide by 2 and we get 7/2. ∴ y = 7/2, x = 2.
