Question

Which linear function represents the line givin by the line point-slope equation y +1 = 3(x-5)

Answer 1

The last one f(x)= -3x + 14

Explanation:

1. Distribute -3x

You get y+1= -3x + 15

Positive 15 because a negative times a negative is a positive

2. Subtract 1 from each side

You get y= -3x +14
