Question

Write the equation of the line with a slope of 3/7 passing through the points (9,-2)

Answer 1

use point slope form
\[y - y_1 = m(x-x_1)\]
where m=slope

does that help? or do you need more hints?

Answer 2

the fraction confuses me i get how to set it up tho

Answer 3

hmm okay set it up...then i'll tell you the next step

Answer 4

y-(-2)=3/7(x-9)

Answer 5

so simplifying that's \[y + 2 = \frac 37 (x-9)\]
right?

Answer 6

then i get lost after that.

Answer 7

ahh you need to get rid of the denominator...you do this by multiplying EACH term by the denominator..in this case 7 so multiply both sides by 7

Answer 8

7y+14=3x-27 right?

Answer 9

correct

Answer 10

now turn it into general form \[ax + by + c = 0\]

Answer 11

would the answer be 3y-7y=41 ?

Answer 12

dont you mean 3x - 7y - 41 = 0

Answer 13

yes but i just move the -42 over

Answer 14

41*

Answer 15

well if in the choices it says = 41 then choose that...but in standard form it';s what i wrote

Answer 16

ok thanks alot!! :)
