Equation of line in point slope form

  • y+1=3(x-2)

A is true

  • y-5=3(x-4)

D is true

Simplify first

  • y=3x-1

And

  • y=3x-7

B is false

Answer:

B. y = 3x -11

Explanation:

the general equation : (y -y1) = s(x - x1)

with a slope = s = 3

the correct equations are :

passes point (2, -1)

=> y+1=3(x-2) => option A is correct

passes point (4, 5)

=> y-5=3(x-4) => option D is correct

<=> y-5= 3x-12

y = 3x-12+5

y= 3x -7 => option C is correct

so, the incorrect equation is option B.

y = 3x -11
