Answer:
No, because the slopes of the lines are not opposite reciprocals.
Step-by-step explanation:
<u>To find out if these lines are perpendicular, find the slopes:</u>
Slope of Green Line: → →
Slope of Yellow Line: → →
<u>For the lines to be perpendicular, the slopes must be opposite reciprocals, which in this case, they are not.</u>

Answer: y = 1 & x = 3
Step 1: Multiply the first equation by -2 so that the equations cancel out the x
-2 ( x + 2y ) = 5
Step 2: Simplify
-2x -4y = - 10
Step 3: Add equations
(-2x - 4y = -10)
+ (2x + 6y = 12)
————————-
2y = 2
Step 4: Simply by dividing both sides by 2
y = 1
Step 5: Substitute y into either equation & simply
x + 2y = 5
x + 2(1) = 5
x+2=5
x=3
