Answer:
total change in time when you used 5 clues is 10.
Step-by-step explanation:
if you have 3 free clues, then 5-3 =2
That means you used 2 additional clues. 2 clues means 5*2 min reduced which is 10 mins reduced. The total time you have is x and the total time left is x-10 after you used the two clues.
Does this help?
Y = 2x-3
The second line will have its Y-Intercept at -3 and its slope will be up 2 and over 1 which will allow it to go through (4,5) and the line will be parallel to Y = 2x+2
I believe this is how you do it
