10. In which of the following tables does each pair of numbers (x,y) satisfy the equation x + 6 = y?

Homework Answers

Where is the origin?!?!

Do You Remember?Which axis is the horizontal axis? _____________Which axis is the vertical axis? _____________

How do you find k?

Goal for TodayFinding K on a graph

DirectVariation

K= Slope When you think of

the word SLOPE…what do you think of?!

Slopes are commonly associated with mountains

The slope we are studying is associated with the graph of a line

Different Slopes Po

sitive

Negativezero

Undefined

POSITIVE SLOPE“Reaching the Goal”

Negative Slope“The Tumbler”

Zero Slope“Not Much Happening”

Horizontal Line

We will only be working with POSTIVE SLOPES

that go through the point (0,0)

K= Rise ÷ Run

Rise= y axis

Run= x axis

What goes first?You need to

rise up before you

run

I. Finding Slope“The Meat of it”

#4Slope:

The steeper the line is the larger K will be!

SO. . . If you graphed each set of equations below, all of the graphs would be straight lines. For each group of equations, the steepest line would be represented by which equation?

A. y = 3x B. y = 9x C y = x D. y = 4x
