Question

What is the equation of the line that passes through (1,5) and (3,1)

Answer 1

4x + 2y - 14

Explanation:

I hope it is understandable.

Answer 2

Below

Explanation:

First let's find m

m = Δy / Δx = y2 - y1 / x2 - x1

= 1 - 5 / 3 - 1

= -2

Now to find b, you can sub in the values of (x,y) for (1,5)

5 = (-2)(1) + b

-b = -2 - 5

-b = - 7

b = 7

Final equation

y = -2x + 7

Hope this helped!
