Answer:
A
Step-by-step explanation:
Remark
The trick here is convert what you have to Ax + By = C
Solution
<u><em>Given</em></u>
y - 3 = 1/2 ( x + 6) Multiply both sides by 2
<em><u>Solve</u></em>
- 2(y - 3) = 2 * 1/2 (x + 6) Do the multiplication
- 2(y - 3) = x + 6 Remove the brackets
- 2y - 6 = x + 6 Add 6 to both sides.
- 2y - 6 + 6 = x + 6 + 6 Combine
- 2y = x + 12 Subtract x from both sides.
- -x + 2y = x - x + 12 Combine
- -x + 2y = 12
Answer
or
- When you multiply through by - 1 you get x - 2y = - 12 which is A

Answer:
A. -4
Step-by-step explanation:
Use the gradient formula (y2-y1)/(x2-x1)
Use the coordinates so (-2,17) = (x2, y2) and (-1, 13) = (x1, x2)
so 17-13/-2--1
= -4
I believe the answer is B. I graphed it and there was only one intersecting point
