find an equation of the line containing the given pair of points
(-2,-1) and (-5,-3)

Question

anonymous · Answer

remember the slope formula?

jim_thompson5910 · Answer

Answer is $$y=\frac{2}{3}x+\frac{1}{3}$$

See attachment for how I got that answer.

anonymous · Answer

It said incorrect

jim_thompson5910 · Answer

what form do they want the equation in?

anonymous · Answer

y=mx+b using integers or fractions

jim_thompson5910 · Answer

how are you entering the answer. Hopefully using an equation editor

anonymous · Answer

it has one built in

jim_thompson5910 · Answer

well what I have is the right answer. I double checked to make sure

jim_thompson5910 · Answer

ok and you're using it?

jim_thompson5910 · Answer

a lot of the times, the computer is really really picky about how you enter the answer

anonymous · Answer

no, you are right, I was on the wrong question

jim_thompson5910 · Answer

k cool

anonymous · Answer

{1/6,-1/3} and {5/6,3} thats the one I am on

jim_thompson5910 · Answer

Answer is $$y=5x-\frac{7}{6}$$

See attached as for how I got that answer.

jim_thompson5910 · Answer

Let me know how it works out

jim_thompson5910 · Answer

I know this is probably completely overwhelming, but just go over these attachments till you get it. Don't worry, just take it at your pace and you'll do fine.

anonymous · Answer

How about (-1,-7) and (-6,-4)

jim_thompson5910 · Answer

Answer is $$y=-\frac{3}{5}x-\frac{38}{5}$$


Again, see image attachment for the work shown.

anonymous · Answer

write an equation of the line containing the given point and parallel to the given line. express your answer in the form y=mx+b

(8,9);x+8y=3

jim_thompson5910 · Answer

x+8y=C
8+8(9)=C
8+72=C
80=C

So the equation is x+8y=80. Now solve for y

x+8y=80
8y=-x+80
y=-1/8x+10

Answer: 

$$y=-\frac{1}{8}x+10$$
