The line of best fit helps you make predictions based upon ordered pairs that you have plotted. The independent variable is on the x axis. The dependent variable is on the y axis. You find the slope by plugging in the order pairs into a calculator which gives you the line of best fit.
Hope this helped :)
Answer:
no it is not a proportional relationship
Answer:
f(x) ≤ -5
Step-by-step explanation:
<h3>
Answer: Second choice. (-5,4)</h3>
Point A is located at (5,4)
To reflect over the y axis, we flip the sign of the x coordinate while keeping the y coordinate the same. The rule is 
So we will have
as the location of A'
