Question

What is the equation of the line that passes through the points (-1, 3) and (1, 11)?

a) 4x - y = 1
b) 4x + y = 1
c) x - 4y = -13
d)4x - y = -7

Answer 1

ok so you know slope formula?

Answer 2

y1-y2 over x1-x2

Answer 3

Well first find the slope, using the following formula: \[m = \frac{ y_{2}-y _{1} }{ x _{2}-x _{1} }\] where your coordinates represent \[(x_1,y_1)~~\text{and}~~(x_2,y_2)\]
Once you manage to get that, plug in m and your first coordinates in the point - slope form: \[y-y _{1}=m(x-x _{1})\] doing some algebra you can put it as the way it's provided in your answers.
