Question

find an equation of the line having the given slope and containing the given point.
m=2/3, (1,-2)

Answer 1

Use the point slope formula

Answer 2

y-y1=m(x-x1)

Answer 3

i thought it was y=mx+b

Answer 4

or is that the same thing

Answer 5

Yes, that's slope-intercept form. You use the point-slope formula to get to slope-intercept form.

Answer 6

iv never heard of the point-slope formula, how do i do it?

Answer 7

Just plug in values and solve for y.
So for this one, it has a slope(m) of 2/3, and the points (1(x1), -2(y1))

Answer 8

Now plug all that into here:
y-y1=m(x-x1)

Answer 9

-2-y1=2/3(1-x1) ?

Answer 10

^_^'

Answer 11

y-(-2)=2/3(x-1)
