Which of the following is equation of the line through (2,3) and (-1,-12)

 y = 5x - 7

Step-by-step explanation:

(x₁ , y₁) = ( 2 , 3)    & (x₂ , y₂) = (-1 , -12)

Slope =

m = 5 & (x₁ , y₁) = ( 2 , 3)

Equation of the line:  y - y₁ = m(x -x₁)

y - 3 = 5(x - 2)

y - 3 =5x - 2*5

y - 3 = 5x - 10

    y = 5x - 10 + 3

   y = 5x - 7

i think c. but don't trust it.

step-by-step explanation:

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
