Answer:
Step-by-step explanation:
y - 7 = -5/2(x - 2)
y - 7 = -5/2x + 5
y = -5/2x + 12
Check the picture below.
that's the line of x = 12, just a straight vertical line, notice the green line, that's parallel to it, and the red line, that's perpendicular to it.
let's pick two points for each to get their slopes, hmm say for the green one (5,2) and (5,4)

and for the red one hmmm (3,2) and (7,2)
If the question is referring to the least common multiple it is 24
JK is perpendicular to LM
∠LNK = 90°
∠MNJ = 90°
Answer:
(2,-1)
Step-by-step explanation:
(2,3) when reflected over the x-axis, it will be (2,-3)
After translation up 2 units, it will be (2,-3+2) = (2,-1)
