Question

What is the equation of the line that passes through the points (-1, 3) and (1, 11)?
Answer
4x + y = 1
x - 4y = -13
4x - y = 1
4x - y = -7
im confused i tried and got D 4x - y = -7

Answer 1

(y2-y1)/(x2-x1) to get the slope

Answer 2

then equation of the line
y-y1=m(x-x1)
m is the slope

Answer 3

m=4 (1, 11)

y-y1=m(x-x1)

y=4x+7

Answer 4

y=4x+7

Answer 5

i guess this the answer u want 4x - y = -7 , just rearrange it to be
y=4x+7

Answer 6

that's how equation of a line is represented
