Question

PLEASE HELP ME

1. Which is the equation to the line passing through points (2, -7) and (5, -1)?

y = 2x - 8
y = - 2x + 9
y = 2x - 11
y = - 2x + 6

2. What is the equation of the line that passes through (12, 4) and is perpendicular to the graph of y = -3 over 4x - 2?

y = 4 over 3x - 12
y = 3 over 4x - 5
y = -4 over 3x + 20
y = -3 over 4x + 13

Answer 1

So, how do you find the equation of a line?

Answer 2

do you know the slope formula ???

Answer 3

y = mx + b?

Answer 4

y=2x-11

Answer 5

ok that is equation what is formula we should use to find slope

Answer 6

oh, well then how did you get y = 2x - 11?

Answer 7

(2,-7) y=2(2)-11
y=4-11
y=-7

Answer 8

to find the slope you should use this formula
now plug these value into the formula then solve
let me know what you get
