Answer:
The expression represents JL is<u> 3x - 2</u>.
Step-by-step explanation:
Given:
JM = 5x – 8 and LM = 2x – 6.
Now, to find expression represents JL.
JM = JL + LM
<em>Subtracting both sides by LM we get:</em>
JM - LM = JL.
JL = JM - LM
Now, putting the expression to get JL:
Therefore, the expression represents JL is 3x - 2.
The best approximation for the solution to this system of equations is (-2.2,-3)
Option C is correct.
Step-by-step explanation:
Solving the system of equations to get the exact value of x:
Let
Putting value of y from eq(1) into eq(2)
So, Value of x is -2.2
The best approximation for the solution to this system of equations is:
x=-2.2 and y = -3
(-2.2,-3)
Option C is correct.

Part (a)
<h3>Answer: y1 and y3 are perpendicular</h3>This is because the two slopes 2 and -1/2 multiply to -1. Perpendicular slopes multiply to -1 assuming neither line is vertical or horizontal.
=====================================================
Part (b)
Graph each line to see where they cross. The three points of intersection are
(0,4)
(2,-2)
(4,2)
The order of the points doesn't matter.
You could also form three systems of equations pairing up the equations, and solving each system. That way you can find the points of intersection. Graphing may be a better and faster route in my opinion. See the diagram below.
