1. is the set of ordered pares a function? explain why or why not. [(1,3),(2,5),(3,7),(1 7)}*

2- Find f(8) if f(x) = 3x - 4.*

3- What is the slope of the line that goes through the points (12,18) and (9,12)*

step-by-step explanation:

ask goog great chance of finding the solution there

none.

m1=5,m2=0

compare the two slopes in the decimal form. if the slopes are equal, then the lines are parallel. if the slopes are not equal, then the lines are not parallel.

no because mercury has a density of 13.6 grams per centimeter squared while gold has 19.32 grams centimeter squared
