Question

Find the equation of the line that passes through points A and B.

y.
AA (1,7)
-X
B (-3,-1)​

Answer 1

y=2x+5

Explanation:

start with by stating your formula: y=MX +C

m= Y2-Y1÷X2-X1

m=-1-7÷-3-1

m=-8÷-4

m=2

substitution

Using A's coordinates

7=2(1)+c

7=2+c

7-2=c

5=c

therefore y=2x+5
