Answer:

The y coordinate is 3

Explanation:

We are given a system of linear equations and we need to find the y coordinate. We will find the y coordinate via substitution.


6x+2y=30


y=0.5x+1

Since we are already given the value of y, we can plug in the value into the 1st equation and solve for x.


6x+2(0.5x + 1) = 30

Distribute 2


6x+x+2=30

Add like terms


7x+2=30

Subtract 2 on both sides


7x=28

Divide by 7


x=4

We now have the value of the x coordinate which we can plug into the second equation which will make it easier for us to find y.


y=0.5(4) +1

Multiply


y=2+1

Add


y=3

So the y coordinate is 3.
