Question

Choose the system of equations which matches the following graph.

a line includes points 0 comma 0 and negative 1 comma 2. A line includes points 2 comma 3 and negative 1 comma negative 2

5x − y = 7
2x − y = 0

5x − y = 7
2x + y = 0

5x + y = −7
2x + y = 0

5x + y = −7
2x − y = 0

Answer 1

A=(0, 0) B=(-1,2)

get an equation for the points. find the slope and then
use the standard form for slope+point

Answer 2

if x goes negative one, then y goes up 2

y = -2x

also A=(0, 0) that's the intercept and it s 0

-2x -y = 0

Answer 3

so is that the answer?

Answer 4

thats part of the answer, i got the equation for one of the pair of points

you need to get the second equationfor the second pair of points

Answer 5

ok thnx btw do you know what a union is?

Answer 6

no clue
