Question

What is the equation of the line that passes through the points (-2, 1) and (1, 10)?

3x - y = -7

3x - y = -5

3x - y = 5

x + 3y = -5

Answer 1

Here's a different way: (sort of)
The slope of the line is \[(y-y_1)/(x-x_1)\], so slope=9/3=3
10=3*1+b
b=7
y=3x+7 which is a different way of writing
3x-y=-7

Answer 2

alright thanks guys!
