Question

What is the slope-intercept form of the function that contains the point (8, 12) and has a slope of −2?

Answer 1

@perl

Answer 2

we can use the 'point slope' form for equation of line

y-y1 = m(x - x1)

Answer 3

there is more than one form for the equation of a line. Another form that comes up often is 'slope intercept' form, y = mx + b

Answer 4

i can do the y = mx + b

Answer 5

ok, then we will have to do some algebra

Answer 6

we are given the slope is -2, so lets plug that in for m

Answer 7

never done algebra before D:

Answer 8

this is an algebra class , right?

Answer 9

math

Answer 10

what do you get when you plug in m = -2
we get
y = -2x + b

Answer 11

we still need to find 'b'

Answer 12

ok
