Question

which of the following is a solution to the equation y = 3x - 1
a. (4,1)
b. (2,5)
c. (4,3)
d. (0,-3)

Answer 1

I believe the answer is A

Answer 2

let's test that

y = 3x - 1

1 = 3*4 - 1 ... plug in (x,y) = (4,1)

1 = 12 - 1

1 = 11 ... this is false, so (4,1) is NOT a solution to y = 3x - 1

Answer 3

hmmm I graphed it out and used 3x as the slope and -1 as the y-intercept, meaning that I put a dot on (0,-1) and then went up three and over 1, so the answer would be (2,-1). My bad!
