Slope Review

When we talk about slope, we are talking about how _____ a line is on a graph.

• long

• steep

• straight

• short

Choose all of the ways that we can use to represent slope.

• m

• Δy over the Δx

• rise over run

• change in the vertical line over the horizontal line

• y₂ - y₁ over x₂ - x₁

To find the rate of change, find the ______.

• slope

• graph

• money

We have learned to find the slope by using:

• a line

• a table

• (x, y) coordinates

• equations

What is the formula for finding the slope?

• y₂ - y₁ over x₁- x₂

• x₁- x₂ over y₂ - y₁

• x₂ - x_{1 over} y₂ - y₁

• y₂ - y₁ over x₂ - x₁

Use the ordered pairs to write the slope formula.

(7, 2) and (9, 3)

• $\frac{9-7}{3\ -\ 2}$

• $\frac{3\ -\ 2}{9\ -\ 7}$
  

• $\frac{3-2}{7-9}$

In this ordered pair, which value is the "x"?

(3, 7)

• 3

• 7

In this ordered pair, which value is found on the vertical axis (the y axis) on a coordinate plane?

(4, -3)

• 4

• -3

A line that increases (goes up) from left to right is:

• positive

• negative

• zero

• undefined

A line that decreases (goes down) from left to right is:

• positive

• negative

• zero

• undefined
