This doesn't represent an function. Because the output is uneven to the other outputs,
1=4, 2=7 if you divided 2 into 2 parts it would equal 1=3.5 not 4.
So for this, I will be doing the elimination method. Firstly, multiply both sides of the first equation by 2:
Next, add the two equations together to get 
. From here you can solve for x.
For this equation, just divide both sides by 8 and your first answer will be 
Now that we have the value of x, substitute it into either equation to solve for y:
<u>In short, the solution is (2,-5), or A.</u>
The equation that show the relationship between Anna earning and time worked is y = 8.5h.
<h3>
Linear equation</h3>
Linear equation is in the form:
y = mx + b
where m is the rate of change, b is the y intercept and y, x are variables.
Let y represent Anna earnings for working h hours.
Since she charges $8.50 per hour to babysit. Hence:
y = 8.5h
The equation that show the relationship between Anna earning and time worked is y = 8.5h.

➷ Use this formula:
Area = ((a + b)/2) x h
a is the top length
b is the bottom length
h is the vertical height
1) Substitute in the values:
((3.8 + 6.2)/2) x 7 = 35ft^2 <== this is the answer
2) Substitute in the values:
((10.3 + 15.1)/2) x 12.6 = 160.02in^2 <== this is the answer
