Question

Which equation is graphed here?
A: y + 5 = -3/2 (x-4)
B: y - 5 = -2/3 (x + 4)
C: y - 5 = -3/2(x + 4)
D: y - 4 = -3/2 ( x + 5)

Answer 2

you got the slope?

Answer 3

no.....

Answer 4

you gotta get that first

Answer 5

you can do it with your eyeballs
i can try to explain how

Answer 6

ok

Answer 7

oh pick a point on the line that is on a corner
doesn't matter which one you pick
i pick \((0,1)\)

Answer 8

-3/2

Answer 9

then see how you get to the next one that is on a corner
you go to the right two, down 3 to get to the next one at \((2,-2)\)

Answer 10

right 2, down 3, slope is \[-\frac{3}{2}\]

Answer 11

Or you could choose two random points and use the formula.
\[m=\frac{ y2-y1 }{ x2-x1} \]

Answer 12

so now we know it is A, C or D didn't eliminate much

Answer 13

lol

Answer 14

if it is y + 5 = -3/2 (x-4)
that means the point \((4,-5)\) is on the graph
is it?

Answer 15

and the answer is no, it is not, so now we got rid of A

Answer 16

if it is y - 5 = -3/2(x + 4)
that means the point \((-4,5)\) is on the graph
is it?

Answer 17

no

Answer 18

then i hope it is the last one

Answer 19

y - 4 = -3/2 ( x + 5) means the point \((-5,4)\) is on the graph
i sure hope so!

Answer 20

actually it is not
did i make some mistake?

Answer 21

ah yes i did \[(4,-5)\] IS on the graph

Answer 22

i said "no" but it should have been "yes"
go with A, i will get my eyes checked

Answer 23

lol thanks!
