Answer:A. (9, –36)
Step-by-step explanation:
A. (9, –36)
There's two ways, you can either multiply 11 and 7 to get 77 and then divide by 2, OR, you can divide 11 by 2 and get 5.5 and multiply that by 7, hope this makes sense, if you don't understand just comment and I'll explain it more :)

For x=3, the denominator is equal to 0 and you can't divide by 0.
Answer:
y - 3 =
(x - 1)
Step-by-step explanation:
slope m = (y₂ - y₁) / (x₂ - x₁)
= (4 - 3) / (-1 - 1)
= 
Point slope form:
y - y₁ = m(x - x₁)
y - 3 =
(x - 1)
can be further simplify:
y - 3 =
+ 
y - 7/2 = -1/2x
