Understanding Slope-Intercept Form

The video tutorial explains how to graph a line using the slope-intercept form, y = mx + b. It identifies the y-intercept (b) and the slope (m) from the equation, demonstrating how to plot the y-intercept on the graph and use the slope to find additional points. The tutorial emphasizes the concept of 'rise over run' to understand the slope and provides a step-by-step guide to plotting the line. It concludes with a brief mention of more complex examples where the equation is not solved for y.

What is the y-intercept in the equation y = -2x + 5?

• -2

• 5

• 0

• -5

In the equation y = mx + b, what does 'm' represent?

• Slope

• Y-intercept

• Constant

• X-intercept

How can the slope -2 be expressed as a fraction?

• -2/1

• -1/2

• 1/-2

• 2/1

What does the slope -2/1 indicate about the movement on the graph?

• Up 1, Right 2

• Down 1, Left 2

• Down 2, Right 1

• Up 2, Left 1

Where do you start plotting the line on the graph?

• At any random point

• At the x-intercept

• At the y-intercept

• At the origin

After plotting the y-intercept, how do you find the next point using the slope?

• Move down 2 and right 1

• Move up 1 and right 2

• Move up 2 and left 1

• Move down 1 and left 2

What is the next step after plotting the y-intercept and using the slope?

• Erase the points

• Draw a horizontal line

• Draw a vertical line

• Connect the points with a straight line

What will be discussed next after graphing lines in slope-intercept form?

• Using slope-intercept form when the equation is not solved for y
