Question

Write the equation of the line in y=mx+b that passes through the points (5,10) and (6,12)

Write your answer as a simplified fraction.

Answer 1

y = 2x + 0 or y = 2x

Explanation:

use slope-intercept form
`(y2 - y1)/(x2 - x1)`

12 - 10 = 2

6 - 5 = 1

m value = 2/1 = 2

y=2x+b

to find b plug one of the points in for x and y

Example: 10 = 2(5) + b

solve equation

10 = 10 + b

subtract 10 from both sides

0 = b

Equation of line equals y=2x+0 or simply just y=2x
