Question

find the equation of the line through the given pair of points in standard form using only integers
(5,-3) and (-2,4)

Answer 1

what is the slope?

Answer 2

y1-y2/x1-x2 ??

Answer 3

-1

Answer 4

slope: m = -1

Answer 5

let's say we pick the point (5,-3)

so x = 5 and y = -3

Answer 6

y = mx+b

-3 = -1*5 + b

solve for b

Answer 7

2

Answer 8

the equation in slope intercept form is y = -1x + 2 or y = -x+2

Answer 9

last step: turn that equation into standard form

Answer 10

x+y+2

Answer 11

=

Answer 12

x+y=2

Answer 13

x+y = 2 is correct

Answer 14

but wait

Answer 15

what's wrong?

Answer 16

my multiple choices are different

Answer 17

A) 7x+7y=14
B) 7x-7y=14
C)7x+7y=14
D)7x+7y=22

Answer 18

are they wrong because the answer we came up with was the one i had origionaly

Answer 19

ok we have x+y = 2

what can we do to both sides to get it to what they want

Answer 20

times 7

Answer 21

A and C are identical and you can simplify

Answer 22

so we would have 7x+7y = 14 when we multiply both sides by 7

Answer 23

which is either A or C

Answer 24

c is -14

Answer 25

the answer is a

Answer 26

so thats what we have to do

Answer 27

ok, then A it is

Answer 28

ok thank you <3
