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

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

Options :

a) f(x) = y=-3x + 13

b) f(x) =y= -3x + 16

c) f(x) = y=-3x + 14

d) f(x) = y=-3x + 18

 

The correct answer is c) f(x) = -3x + 14

Solution:

y + 1 = –3(x – 5)

y+1 = -3x+15

y= -3x+15-1

y= -3x+14

f(x)=y= -3x+14
