Question

What is the equation of the line containing the points (-1,3) and (2,9)

Answer 1

Answer:

y = 2x + 5

Step-by-step explanation:

First,

9-3 = 6

over

2-(-1) = 3  

Then,

6 divided by 3 = 2

2 = slope

Next, using (-1,3), *you can use either ordered pair

y - 3 = 2 {x - (-1)}

y - 3 = 2x + 2

y = 2x + 5
