If x =-4 and y =4 3x+ y over xy - 3x = what

-2

Step-by-step explanation:

We start out our equation by plugging in the values for x and y which becomes:

3(-4) + 4 over -4(4) - 3(-4)

So basically we just simplify both the numerator and denominator which equals:

-12 + 4 over -16 + 12

Simplify it even more:

-8 over -4 or -8/-4

Which gives us the

-2

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.
