Question

Determine the standard form of the equation of the line that passes through (7, -1) and (3, 9).
a. 5x +2y= 33
b. 2x+5y = 33
c. 5x-2y=33
d. 5x+ 2y=-33

Answer 1

can u find slope first ?

Answer 2

umm hold on yeah

Answer 3

-5/2=-2.5? That's what I got but I get stuck after getting the slope

Answer 4

the equation of line can be written as y-y1=m(x-x1)
since u have slope, u just need one point, (x1,y1)
u have 2 points, take any 1 of those as (x1,y1)
and substitute in y-y1=m(x-x1)

Answer 5

So the answer is d?

Answer 6

did u guess that ?

Answer 7

No that's the answer I got from the beginning but I was unsure....

Answer 8

yup, its D

Answer 9
