What is the solution to this system of linear equations? y − x = 6 y + x = −10 (−2, −8) (−8, −2) (6, −10) (−10, 6)

Start with

If we sum the two equations, we have

which implies

So, the solution is (-8,-2). In fact, plugging these values in the two equation gives

which are both true identities

 the correct option is (B) (-8, -2).

Step-by-step explanation:  We are given to find the solution to the following system of linear equations :

We will be solving the given system of equations by elimination method.

Adding equations (i) and (ii), we get

And, from equation (i), we get

Thus, the required solution is (x, y) = (-8, -2).

Option (B) is CORRECT.

step-by-step explanation:

i hate black

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
