Answer:

Step-by-step explanation:

Express the equation in slope- intercept form

y = mx + b ( where m is the slope and b the y- intercept )

Here m = - 0.5, thus

y = - 0.5x + b

To find b substitute (10, 1) into the equation

1 = - 5 + b ⇒ b = 1 + 5 = 6 ← y- intercept

To answer this you can use a guess and check strategy.

Start with 5 minutes using it (25% lost) and 10 minutes charging (20% gained).

Try 7 minutes using it (35% lost) and 14 minutes charging (28%).

Next, 9 minutes (45%) and 18 minutes(36%).

10 minutes (50%) and 20 minutes (40%). This is the difference.

She used it for 10 minutes and charged it for 20 minutes.

Answer:

Step-by-step explanation:
