What's NOT true when you see an equation in this form?

• The a value is the y-intercept

• If the b-value is greater than 1, that means the function is increasing

• If the b-value is less than 1, that means the function is decreasing

• The b-value is the x-intercept

How do you know where the shading on the graph should be?

• If y is greater, it should be shaded above. If y is less, it should be shaded below. If y is negative, flip the sign before you shade

• If y is greater, it should be shaded below. If y is less, it should be shaded above

• If x is greater, it should be shaded above. If x is less, it should be shaded below

• If the line is dotted, it should be shaded above. If the line is solid, it should be shaded below

How should you solve a SYSTEM OF EQUATIONS like this one?

• Use Menu 413 to find the slope of both

• Put them both in nsolve and multiply the answers

• Change them to y = form, graph them, and find where they cross

• Guess an x and y value and plug in to check if they work

When we're talking about QUADRATICS (the smiley face looking graphs), what does the word "solutions" mean?

• vertex

• y-intercept

• x-intercept(s)

• axis of symmetry

If you're stuck, but you have nothing to graph, try..............

• giving up

• eating soup

• writing 2 equations based on the problem so then you'll have something to graph

• adding all the numbers in the problem and then dividing by 4
