Graphing a linear equation in slope intercept form

The video tutorial explains how to graph a linear equation in slope-intercept form. It begins by identifying the slope and Y-intercept, then demonstrates how to plot the Y-intercept on a graph. The tutorial continues by explaining the concept of slope as a ratio of change in Y over change in X, and how to use it to find additional points on the graph. Finally, it shows how to draw the line through the points and extend it in both directions, emphasizing that only two points are needed to define the line.

What is the y-intercept of the equation 2X + 1?

• (1, 0)

• (0, 1)

• (0, -1)

• (1, 1)

How is the slope of the equation 2X + 1 represented?

• -2/1

• 1/2

• 2/1

• -1/2

If the slope is -2, what is the next step after plotting the y-intercept?

• Move down 1 unit and right 2 units

• Move up 2 units and left 1 unit

• Move down 2 units and right 1 unit

• Move up 1 unit and left 2 units

What does the line on the graph represent?

• All points that satisfy the equation

• A single point on the graph

• Only the y-intercept

• Only the x-intercept

Where is the x-intercept estimated to be located?

• Between 1 and 2

• At 1

• At 0

• Between 0 and 1
