PLEASE HELP FAST which is not an equation of the line going through (6,7) and (2,-1)?

A. y + 1 = 2(x - 2)

B. y - 1 = 2( x + 2)

C. y - 7 = 2(x - 6 )

D. y = 2x - 5

the discriminant is 64 + 4*1*12 = 112

this is prime.

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.

i think the answer is b

the answer is a. q=6,r=6√2
