Question

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

Answer 1

Answer:

f(x) = –3x + 14

Step-by-step explanation:

y + 1 = -3(x - 5)           use the distributive property: a(b + c) = ab + ac

y + 1 = (-3)(x) + (-3)(-5)

y + 1 = -3x + 15       subtract 1 from both sides

y + 1 - 1 = -3x + 15 - 1

y = -3x + 14
