Question

Choose the slope-intercept equation of the line that passes through the point (-5, -1) and is perpendicular to y = 5/2 x + 2.

Answer 1

Answer 2

Ooh perpendicular equation.. I got this(:

Answer 3

lines that are perpendicular have negative reciprocal slopes

Answer 4

so the new line would have a slope of -2/5

Answer 5

Oh yes, the explaining would help me majorly as well - I have several more of these types of questions :3 ♥

Answer 6

right :D

Answer 7

and we can put this information into point-slope form

Answer 8

& I would like to be able to understand them, lol

Answer 9

y - y1 = m(x - x1)

so we're given this point, (-5, -1) and we can plop that in the equation along with the slope

y + 1 = -2/5(x + 5)

now put that into slope-intercept form, sam

Answer 10

slope-intercept form being y = mx + b
first you gotta distribute that -2/5

Answer 11

ari wins, I'm no good at explaining this >_<

Answer 12

Ok, so you would have: y + 1 = -2/5m - 2
That's what as far as distributing the -2/5 and I have a feeling thats wrong...
