Is the ordered pair left parenthesis 4 comma negative 1 right parenthesis(4,−1) a solution of the following system of equations?
3 x plus 5 y equals 73x+5y=7
5 x minus 3 y equals 175x−3y=17

No

Step-by-step explanation:

(x,y)=(4,-1)

73x+5y=7

73*4+5*(-1)=287

____________________________

175x−3y=17

175*4-3*(-1)=703

step-by-step explanation:

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.
