Any coordinates in the shaded area are solutions. Any coordinates on the line are not a solution due to it being dashed. Anything in the non-shaded area is also not a solution. You can always check if you are right by plugging in the numbers.

Example: (1, -2)

-2 < 0.5(1) + 2

-2 < 0.5 + 2

-2 < 2.5

True, -2 is less than 2.5.

Another Example: (-2, 1)

1 < 0.5(-2) + 2

1 < -1 + 2

1 < 1

False, 1 is not less than itself.

The table shows the relationship between the number of Calories Lucie burns while jumping rope and the number of minutes she jum

iragen [17]

Answer:

The amount of calories Lucie will burn by jumping for 1 minute is 8 calories

Step-by-step explanation:

The given data values are;

Minutes ${}$ Calories Burned

40 ${}$ 320

80 ${}$ 640

120 ${}$ 960

160 ${}$ 1280

The value of calories burnt and the number of minutes of jump robe are seen to be directly proportional, such that we have;

40 minutes of jump rope will yield 320 calories burnt

Therefore we have;

1 minute of jump rope will yield 320/40 = 8 calories burnt

The amount of calories Lucie will burn by jumping for 1 minute = 8 calories.
