Graphing in a Variety of Contexts

Question 3 • WI-Mathematics Grade 8 A

Identify where the given information is sufficient for graphing a linear equation. Check all that apply.

Answer
A
one point and the slope of the line
B
one point
C
one of the intercepts and the slope of the line
D
both the intercepts
E
two points

Explanation

A point and a slope determine a line, so one point with the slope is enough. An intercept is a point on the line, so an intercept plus the slope also determines it; both intercepts give two points, and two points determine a line. One point by itself is not enough because many different lines can pass through it.
