Answer:
The relation is <u>not</u> a function.
Step-by-step explanation:
A function is a relation in which no two ordered pairs have the same input and different outputs. Whenever you're trying to determine whether a given relation is a function, observe whether each input corresponds with <u><em>exactly</em></u> one output.
In this case, the answer is no. The input value of 10 corresponds with two output values, 4 and 20. It only takes one input value to associate with more than one output value to be <u>invalid</u> as a function.
Therefore, the given relation is <em><u>not</u></em> a function.
To find the midpoint you find the average x and the average y values. The average of 1 and 9 is 5, and the average of 4 and 16 is 10. The midpoint would be (5,10).

Answer:
Step-by-step explanation:
1,)
3x+y=4 <-Equation 1
2x-y=6 <-Equation 2
Step 1 Eliminating Y Multiply negative both side
-[3x +y = 4 ] -
-3x-y = -4 <-Equation 3
Equation 2 to Equation 3
2x-y=6
-
-3x-y = -4
= 5x = 10
x =2
Substituting X to Equation 1
3x+y=4
3(2) + y =4
6 + y = 4
y = -2
Therefore x =2 and y = -2
