Which line on the graph below has an undefined slope?

lukranit [14]

Answer:

Step-by-step explanation:

A vertical line has slope that is "undefined". Line R is the vertical line on your graph.

_____

The slope of a vertical line is "undefined" because of the way slope is defined. Slope is the vertical change divided by the horizontal change. When the line is vertical, there is no horizontal change, so the computation of slope involves division by zero. The result of division by zero is "undefined."

HELP PLEASE!!!!!! I need help Urgent Help

This is just a porportion. So if 250 meters is 1 meter than: 250/1

And it wants to know the height. So we have the first number but not the second. So we'll use x: 212/x

Set them equal to each other 250/1=212/x

Cross multiply: 212=250x

Divide to find x: 212/250=x
x=212/250
x=0.848

So the height of the model, to the nearest 10th would be 0.8 meters.
