Question 5

To create an equation from a table use LISTS & SPREADSHEET, DATA & STATISTICS, MENU 4, 6, 1.

To create an equation from a graph choose two points and use LISTS & SPREADSHEET, DATA & STATISTICS, MENU 4, 6, 1. Or, you can also create the equation by using SLOPE-INTERCEPT FORM y = mx + b. Find the slope from RISE/RUN and the Y-INTERCEPT by checking where it crosses the y-axis.

Question 6

Since they are asking you to create a system of equations, it helps to separate the problem into two equations that focus on WHAT they are talking about and THE COST of what they are talking about. Make sure the numbers make sense with the variables and the total. Call me for help if you don't understand.

Question 8

When it asks which ordered pair is in the solution set, substitute them into the inequality and check which one is true.

Example: B (6, -5)
$$y>-\frac{1}{6}x-4$$

$$\left(-5\right)>-\frac{1}{6}\left(6\right)-4$$

Notice how I replaced the x and y from the ordered pair into the inequality. Do this to all the answer choices and check which one is TRUE.

You can also check which one will be in the solution set if you were to shade the graph.

Question 9

You can GRAPH STANDARD FORM equations by typing them like this:

$$nsolve(2x=6-y,y)$$

Press TAB to add a second equation.

$$nsolve(5x-4y=28,y)$$

Then check which answer choice matches the one on your calculator. Make sure to verify by checking the point where they cross (intersection) by using MENU, ANALYZE GRAPH, INTERSECTION.
