Question

What is the equation of the line that includes the points (1,6) and (2,8)?

Answer 1

Answer: y = 2x + 4

Explanation:

y = mx + b

(1,6) and (2,8)

Finding Slope:

(8 - 6) / (2 - 1)

=> 2/ 1 or 2

y = 2x + b

Finding "B":

y = 2x + b

=> 6 = 2(1) + b

=> 6 = 2 + b

=> b = 4

so y = 2x + 4
