Question

What is the equation of a line that passes through (1, 8) and (2, -4)?








a.y - 8 = 12(x - 1)
b.y - 8 = -4(x - 1)
c.y - 8 = -12(x - 1)
d.y - 8 = 4(x - 1)

Answer 1

do u know 2 point form for equation of line ?

Answer 2

yes

Answer 3

so did u substitute those points in the formula?
where exactly are u stuck?

Answer 4

im stuck on how to find the equation i don't know how to get it

Answer 5

did u find whats (y2-y1)/(x2-x1) ??

Answer 6

Yup....1st find the slope

Answer 7

how do you find slope?

Answer 8

(y2-y1)/(x2-x1)
