About this worksheet

What students practice

Students use coordinate differences and the Pythagorean Theorem to find distances between response points.
Students compare exact and approximate distances to interpret and check survey graphics.

How to use

Have students sketch horizontal and vertical legs before finding distances. Allow a calculator for rounding questions, then discuss what distance can and cannot tell readers about opinions.

Curriculum

Common Core standard covered

8.G.B.8

Student Opinion Poll: Distance Desk

Use coordinate distances to compare survey responses.

Read the Opinion Plots

The school newspaper surveyed opinions about two proposals. The x-coordinate rates a later lunch period; the y-coordinate rates a longer advisory period. Each rating runs from −5 (strongly oppose) to 5 (strongly support). Distance means straight-line distance between score points, measured in coordinate units—not a physical distance. Use the Pythagorean Theorem.

The plot shows responses from two students. How far apart are their response points?
