Question

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

Answer 1

Answer:

Step-by-step explanation:

m = (y2-y1) / (x2-x1)

m = (-5--1) / (5-3) = -2  

note that it does not matter which points you chose to be second or first

then use slope point equation again it does not matter which point from the slope you use

y - y1 = m ( x - x1 )  

y - (-1) = -2 ( x - 3)  

y = -2x + 6 - 1

y = -2x +5
