Question

What is the linear equation if the line passes through points (4,5) and (6,9)?

Answer 1

(4,5) and (6,9) have a line through them with slope = (9-5)/(6-4) = 4/2 = 2

y = (2)x + b

plug in either point to solve for b

5 = (2)(4) + b

b =5-8= -3

y =2x -3 is the equation through the points (4,5) and (6,9)
