if (2,-3) is the solution of the equation 2(x+1)-7(y-2)=k, find the value of k and find two more solutions​

210

Step-by-step explanation:

Just plug in for X and Y and solve the equation.

2(2+1)-7(-3-2)=k

2(3)-7(-5)=k

(6)(35)=k

210=k

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.

not sure but it may be b, as i said i'm not sure.
