Answer:
-2
Step-by-step explanation:
2x + y = 10 Subtract 2x from both sides.
2x-2x + y = 10 - 2x Combine the left.
y = 10 - 2x
The slope is the number in front of the x -- in this case - 2
The answer is - 2
Opposite sides are congruent and have the same slope.
If x people were surveyed then 42% *x=210
210/42%=500=x
Therefore, 500 people were surveyed
Break it down it’s a lot easier
