The top one shows they are parallel lines because it shows angles of both lines and the transversal
Answer:
Undefined.
Step-by-step explanation:


The denominator is 0. Therefore, the slope is undefined.
Answer:
This is curve sketching which is used in math
Step-by-step explanation:
we can see a graph plotting with the equation...of all sides
D = 900t
because if you want to simplify t (2 hours) into one then you divide 1800 by 2 and that gives you the constant of proportionality (slope) of 900. Using this information you can write the expression d = 900t.
Example (not a very likely example, however):
At 11 pm the temperature is -15 degrees F, and it continues to drop by 10 degrees F every hour.
