Answer:
x = - 2
Step-by-step explanation:
Don't let the points disturb you. They are actually meant to confuse you.
Given: We have the given figure through which we can see
LK=16,
KJ=10,
LM=24,
MN=15
To Find: Whether KM || JN and the reasoning behind it.
Solution: Yes, KM || JN because 
Explanation:
For this solution, we use the concept of Similar Triangles.
Now, KM || JN if ΔLKM ~ ΔLJN (i.e., if ΔLKM is similar to ΔLJN).
Now, ∠MLK=∠NLJ
To prove similarity of the two triangles, we have to show that the sides are proportional. In other words, LK:KJ = LM:LN

which is true as both sides simplify to 
Thus, we see that ΔLKM ~ ΔLJN (i.e., if ΔLKM is similar to ΔLJN).
Therefore, KM || JN.
To come to the reasoning, notice that

In other words, 
Answer:
y = 2/3x - 13
Step-by-step explanation:
We have a slope of 2/3 and a point (9, -7)
The point slope form of a line is
y-y1 = m(x-x1)
y--7 = 2/3 (x-9)
Distribute
y+7 = 2/3x - 6
Subtract 7 from each side
y+7-7 = 2/3x -6-7
y = 2/3x - 13
This is in slope intercept form.
Answer: y = -x - 1
<u>Step-by-step explanation:</u>
Use the Point-Slope formula:
where
- (x₁ , y₁) is the given point (0, -1)

Insert those values into the formula and solve for y:
y - (-1) = -1(x - 0)
y + 1 = -x
y = -x - 1
