Question

A graph has two lines that show proportional relationships. The line with a higher slope has a larger _________.

• A. run
• B. rise
• C. length
• D. unit rate

Answer 1

The correct option is D unit rate


Here, slope of the red line $>$ slope of the green line.
Unit rate for the red line $=2\text{miles/hr}$
Unit rate for the green line $=1\text{mile/hr}$
Thus, the unit rate for the red line $>$ unit rate for the green line.
Thus, the line with a higher slope has a larger unit rate.
