To test a graph for a function we use what?

The vertical line test!

100

What are we solving for in a equation?

The variable (x)

100

What is the y intercept?

Where the line crosses the y axis

100

What is slope intercept form?

y = mx + b

100

To convert a fraction to decimal you...

Divide the top by the bottom!

200

The definition of a function is...

Every x value has one and only one y value

200

What is the value of x?

3x + 1 = 7

x = 2

200

What are 3 names we use for slope?

m

k

Rise/Run

Rate of Change

Change in y/Change in x

200

Find the missing side!


x = 10.7

200

A proportional graph needs...

To be straight and go through origin

300

What do we care about when looking for functions?

The x values!
300

What is the value of y?

-2y + 1 = 3y - 4

y = 1

300

What is the first step to finding slope on a graph?

Find two points!

300

Find the lateral surface area! (S = Ph)


S = 126 ft squared 

300

The slope of the table is...


m = 4

400

Is the image a function? Why?

No! 7 has two lines which means x repeats!

400

What is the value of n?

1.4n + 3.2 = 6.2n - 6.4

n = 2

400

If I start in Q1 of a graph and reflect across the x axis, where is my shape?

Q4

400

If y varies directly with x, what is the constant of proportionality when y = 2 and x = 8? (y=kx)

k = 1/4

400

Find the slope of the points (3, -2) and (0, 4)

(m = y2 - y1/x2 - x1)

m = -2

500

Is the following a function? Why?


Yes! The x values do not repeat

500

DAILY DOUBLE!

What is the value of x?

4x - 2x = 10 + 7x - 5

x = -1

500

If I start in Q2 and rotate my shape 270 degrees clockwise, where is my shape now?

Q3

500

Find total surface area! (S = 2πrh+2πr^2 )

Remember r is half of d!


S = 401.92
