Question

Write the equation of a line in slope-intercept form that has a slope of -2 and passes through the point (2, -8).

A. y = -2x - 4
B. y = -2x - 8
C. y = -2x + 18
D. y = -2x – 14

Answer 1

ok, first put it into point-slope form and then rewrite it into slope-intercept

Answer 2

point-slope: y - y1 = m(x - x1)

Answer 3

how do you know which number goes where?

Answer 4

all coordinates are setup as (x,y)

Answer 5

so the first number in the pair would be x1

Answer 6

and the second would be y1

Answer 7

and of course, m is whatever the slope is

Answer 8

it would be B? right?

Answer 9

no

Answer 10

ohh, i think i fied my problem but mybe not. they way i have it worked out it should be A

Answer 11
