Question

Select the system of equations that corresponds to the given graph.
( the graph is under the answers in the attachment)


-2x - y = 4
2x + y = -2


-8x - 4y = 16
-4x - 2y = 8


x - 2y = 6
-2x + y = 4


2x + 3y = 6
3x + 2y = 4

Answer 1

Ok so you notice that the 2 lines in the graph are the same. can you give me the equation of the line

Answer 2

not really. i dont understand graphs. thats why i need help

Answer 3

ok so a line on a graph has the form y=mx+c. m is the gradient*change in y divided by change in x) and c is the y intercept(where it cuts through the y axis.

Answer 4

see the lines cut the axis's on two points
use them to get the equation

Answer 5

so pick 2 points on thee graph. say u have (1,2) and (3,5) the gradient would be change in y so 5-2=3 divided by change in x so 3-1=2 so gradient =3/2 You have to choose 2 points on the line and do what i just did there to get the gradient
