Question

The tables below show solutions for two linear equations. If the two equations make up a system of linear equations, in which quadrant is the solution?

Quadrant one

Quadrant two

Quadrant three

Quadrant four

Answer 1

FAN AND MEDAL :)

Answer 2

If they're linear and you're given several points, you can find the equation of each function by using the formula y=m(x-p)+q.

Answer 3

You can then create a system of equations by making the two y values equal to one another, I'm guessing.

Answer 4

The sol'n then should allow you to figure out some values and assign the values a quadrant accordingly. I think that's how you approach this problem.

Answer 5

??

Answer 6

are you able to find the equation of each line?

Answer 7

me? no, I dont really understand what she said...

Answer 8

how about the slope? are you able to find that?

Answer 9

um, no... i'm not really good at this sort of thing

Answer 10

y=mx+b, m is the slope. D:

Answer 11

are you familiar with the slope formula

m = (y2 - y1)/(x2 - x1)

??

Answer 12

no, i never learned the formulas for this

Answer 13

for the first table, pick two points and tell me which points you picked

Answer 14

-7 and 3

Answer 15

so that's one point (-7,3)

what's another?

Answer 16

-10 and 9

Answer 17

(-10,9) is another point

Answer 18

All points are of the form (x,y)

Answer 19

So the point (-7,3) means x = -7 and y = 3

The point (-10,9) means x =-10 and y = 9

Answer 20

yup.

Answer 21

hold, on im going to try now

Answer 22

ok

Answer 23

i got quadrant 1

Answer 24

What did you get for the slope?

Answer 25

linear

Answer 26

you should have gotten a number for the slope

Answer 27

We have a system of equations. If there's a solution, it's where the lines represented by those equations intersect. Plot the points given, draw a straight line through them. Observe where they intersect.
