Answer:

B. y=-x-3

Step-by-step explanation:

[tex]f(x) = ax + b \\ a = - 1 \\ (x \: y) = ( - 5 \: \: 2) \\ f( - 5) = - ( - 5) + b = 2 \\ 5 + b = 2 \\ b = - 3 \\[/tex]

So,

[tex]f(x) = - x - 3 \\ y = - x - 3[/tex]

Hope it helps

Equation in point slope form

  • y-y1=m(x-x1)
  • y-2=-1(x+5)
  • y-2=-x-5
  • y=-x-3
