Question

indicate the equation of the line through (2,-4) and having slope of 3/5

Answer 1

_x__y=____

Answer 2

whats the equation for a line?

Answer 3

i just dont get that form they have it in....

Answer 4

well I'm not exactly good at this, but couldn't you just plug it into y = mx + b

Answer 5

so I think you might use this equation y - y1 = m(x - x1)

Answer 6

plug the -4 into x1 and the 2 into y1

Answer 7

ok

Answer 8

then plug the slope into m

Answer 9

so y+4 = 3/5(x-2)

Answer 10

then distribute the 3/5

Answer 11

so y + 4 = 3/5(x) - 3/5(2)

Answer 12

which is y + 4 = 3/5(x) - 6/5

Answer 13

got that ..

Answer 14

subtract 4 from both sides to isolate y

Answer 15

so y = 3/5(x) - 6/5 - 4

Answer 16

combine the terms and end up with: y = (3/5)x -26/5

Answer 17

ok thank you!

Answer 18

hope it's right :O
