CCSS.8.F.A.3

What is the domain and range of this line?

What is an x-intercept?

• a point

• a line

• a random number

Every single coordinate point along the x-axis has a y value of _____.

• 1

• 0

• -1

• I don't know

Every single coordinate point along the x - axis has a y value of _____.

• 0

• 1

• -1

• I don't know

Now that you know what an x-intercept is, what do you think a y-intercept is?

Every single coordinate along the y-axis has an x value of _____.

• -1

• 1

• 0

• y

CCSS.HSF.IF.A.1

A coordinate point on a line is _______ to the equation.

• a random coordinate

• a solution

• the point isn't on the line

How many points (minimum) do you need to graph a line?

• 0

• 1

• 2

• 3

The first method he showed was:

• plug in 0 for x or y depending on which intercept you are finding and solve

• guess and check

• pick a random point on the graph
