Question

How do I find the point slope when I only have a slope and a y-intercept?

Answer 1

for ex: slope= -5, y-intercept=-8

Answer 2

if you know the slope and the y intercept; you can plug in values for x to get the value for y

Answer 3

y = -5x - 8

Answer 4

that's your slope intercept form; do you know the formula for point slope?

Answer 5

omg thanks, that was easy lol, >.<

Answer 6

You're welcome

Answer 7

Sometimes I get confused :p

Answer 8

oh no wait

Answer 9

Just to be clear, the equation I gave you isn't the final answer.

Answer 10

I am looking for the point slope

Answer 11

Yeah I just realized lol

Answer 12

sorry

Answer 13

I need to find the x intercept

Answer 14

right?

Answer 15

to find the x int you set y = 0

Answer 16

ok

Answer 17

But really you just need to rearrange to slope intercept form I gave you.

Answer 18

rearrange it to

\[(y-y _{1}) = m(x-x_{1})\]

Answer 19

yes,but what do i put for x?

Answer 20

(y-(-8)=-5(x-?)

Answer 21

Try substitution values in the for x in the slope intercept form; then plug those values into the point slope form. m or in this case, -5, does not change

Answer 22

I'm confused.
