Question

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

Answer 1

slope: (11-3) / (1-(-1) = 4
y=4x+b
1 = 4(11) + b
1 = 44 + b
b = -43

equation: y= 4x-43

Answer 2

But that's not in one of my options..? @jayz657

Answer 3

sorry i made a mistake
it is 11 = 4(1) + b
11=4 + b
b = 7

equation: y= 4x +7

Answer 4

The one I have similar to yours is 4x - y= -7 @jayz657

Answer 5

yea its the same as the one i have
