To find whether a pair is a solution of an equation, you plug in x and y by their respective value and if their is an equality, then it's a solution:

y = 2x+1
Is F(3,7) a solution? 7 = 2(3) +1 → 7 = 7 . YES, F(3,7) is a solution

Is G(0,1) a solution? 1 = 2(0) +1 → 1 = 1 . YES, G(0,1) is a solution

Is H(-1,1) a solution? 1 = 2(-1) +1 → 1 = 1 . YES, H(-1,1) is a solution

Is I(-3,-5) a solution? -5 = 2(-3) +1 → 5  ≠ -5 . NO, I(-3,-5) is NOT a solution

The graph shows the relationship between the number of strawberries eaten and the approximate number of calories consumed. Which
Mandarinka [93]

9514 1404 393

Answer:

  Each strawberry contains 4 calories

Step-by-step explanation:

The graph crosses the vertical line for 1 strawberry above the intersection with the horizontal line for 3, so there are more than 3 calories in 1 strawberry. The graph crosses "strawberries = 1" at about "calories = 4", matching the first statement.

Similarly, the graph crosses the vertical line for 4 strawberries above the horizontal line for 15 calories. An estimate of 16 calories for 4 strawberries is consistent with the first statement (4 calories in each strawberry).

The point (6, 24) is on the graph, but it means (6 strawberries, 24 calories), not the other way around.

The appropriate choice is ...

  Each strawberry contains 4 calories
