Answer:
the function given
for 4 units up, just add 4 as a constant
4 units up means, every old value will now be 4 more than previous value. at x=0, y=0 in the transformed curse it should x=0 and y=4, so just add it.
for 6 units left,
each old value of y should now occur 6 units before the old value of x i.e. X=x+6
for example, the point (0,0) should occur at (-6,0) in the transformed graph,
hence,
so the final curve is

Answer:
Ava and Liam have the same amount of money at 10th week.
Step-by-step explanation:
Given:
Amount Ava has in her piggy bank = $110
Amount spends per week = $5
Let the number of weeks be 'w'.
So we can say that.
Total amount Ava had after 'w' weeks =
Also Given:
Amount Liam has in her piggy bank = $20
Amount earns per week = $4
Let the number of weeks be 'w'.
So we can say that.
Total amount Liam had after 'w' weeks =
Now we need to find the number of weeks when both will have same amount.
So we can say that;
Total amount Ava had after 'w' weeks =Total amount Liam had after 'w' weeks
Combining like terms we get;
Dividing both side by 9 we get;
Hence Ava and Liam have the same amount of money at 10th week.
to get the equation of a line, we simply need two points, say for the Red one ... notice in the graph the lines passes through (0,2) and (-1,6), so let's use those
now, for the Blue one, say let's use hmmm it passes through (0,2) and (1.6)
