Graphical data questions are common on the GED Math test, and may involve graphs, histograms, tables, and number lines. In the following practice questions, you're first asked to evaluate a graph that shows the relationship between a patient's sugar intake and their blood sugar level, and then to build and solve an equation from a number line.

Practice Questions

A doctor measured the blood sugar levels of one of her patients shortly after giving the patient a candy bar to eat. The following graph shows the patient's blood sugar level (y), x hours after she ate the candy bar.

ged-blood

How long after eating the candy bar was the patient's blood sugar level the highest? A. 20 minutes B. 30 minutes C. 40 minutes D. 1 hour
The next question is based on the following graph.
What is the product of A times C times D times E? A. –126 B. 0 C. 63 D. 126

Answers and Explanations

The correct answer is C.
According to the graph, the patient's blood sugar began to increase immediately after she ate the candy bar and reached a peak after 2/3 of an hour (40 minutes) before falling again. Hence, Choice (C) is correct.
The correct answer is B.
From the line graph, you can see that A = –9, C = 7, D = 0, and E = –2. Therefore, A times C times D times E equals (–9)(7)(0)(–2). Multiplying any number by zero equals zero, so Choice (B) is the correct answer.
