What is the rule of the function table?

y = 3x - 2

Step-by-step explanation:

The 'rule' of a function table is the expression which you use to put in a value of 'x' to get the value of 'y'.  In this case you can look at the table and look for a pattern of 'x' and 'y' values:

       +1  +1  +1  

x = 1    2    3    4  

y = 1    4    7    10

      +3   +3   +3

So, the 'x' is increasing by 1 each time and the y is increasing by 3.  However, what is 'y' when 'x' is 0?  Subtract 1 - 0 to get x = 0 and subtract 1 - 3 to get the value of 'y' or y = 1-3 = -2.  

If we multiply x by 3 and subtract -2:  3x - 2, then we should get our value of 'y' each time:

y = 1(3) - 2 = 1

y = 2(3) -2 = 4

y = 3(3) - 2 = 7

y = 4(3) - 2 = 10

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x
