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

\(y\) intercept \(-8\) means the point is \((0,-8)\)

Answer 3

you don't need the "point - slope" formula if you know the slope is \(m\) and the \(y\) intercept is \(b\) the equation for the line is \(y=mx+b\)

Answer 4

OHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH

Answer 5

So the x intercept is 0

Answer 6

no

Answer 7

the \(x\) intercept is where the line crosses the \(x\) axis

Answer 8

but if i know the slope is \(2\) and the \(y\) intercept is \(5\) then i know the equation is
\[y=2x+5\]

Answer 9

I mean if I wear to set up the point slope, it's be: (y-(-8)=-5(x-0) ?

Answer 10

it'd*

Answer 11

you could, but you wouldn't

Answer 12

you would go right to \(y=-5x-8\)

Answer 13

Oh ok, but they are asking me for a point slope

Answer 14

k, then you would write what you write, or \(y+8=-5x\)

Answer 15

oh ok

Thank you :D
