What is the solution to the system?

Line 1
x y
–2 –4
–1 –1
Line 2
x y
2 3
3 1

Answer 1

well you wanna get the equations of the lines first. so to do that, we're gonna get the slope of line 1 first. so use the two points (-2, -4) and (-1, -1) and put them in the slope formula \[\frac{ y _{2}-y _{1} }{ x _{2}-x _{1} }\]

Answer 2

it says this

Answer 3

yes i know the question. but you need the equations of the lines first

Answer 4

so what's the slope of line 1?

Answer 5

not sure

Answer 6

Well, looks like u have a Mathlete helping you .-.

Answer 7

from the table, we see two points on line 1, (-2, -4) and (-1, -1). use those points and plug them into the slope formula, which is \[\frac{ y _{2}-y _{1} }{ x _{2}-x _{1} }\]

Answer 8

1

Answer 9

1,2 @AriPotta

Answer 10

\[\frac{ -4-(-1) }{ -2-(-1) }=~\frac{ -4+1 }{ -2 + 1 }=~\frac{ -3 }{ -1 }=~3\]so the slope is 3

Answer 11

oh ok but whats the answer then

Answer 12

i'm not giving you the answer

Answer 13

now that we know the slope is 3, we're going to use that and one of the points into point-slope form, which is y - y1 = m(x - x1)

Answer 14

so its 3,1
