Plotting Lines using Slope-Intercept

The video tutorial explains how to plot a linear equation in slope-intercept form on a graph. It begins with an introduction to the equation y = 7x + 2, explaining the components of the slope-intercept form. The tutorial then guides viewers through plotting the y-intercept and using the slope to determine additional points on the graph. Finally, it demonstrates how to draw the line through the plotted points, completing the graphing process.

What is the slope in the equation y = 7x + 2?

• 7

• x

• y

• 2

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

• The origin

• The x-intercept

• The y-intercept

• The slope

Where should you start plotting a line on a graph when given the equation y = mx + b?

• At any random point

• At the x-intercept

• At the origin

• At the y-intercept

How do you determine the next point on a graph using the slope?

• By guessing the next point

• By using the rise over run method

• By moving horizontally by the slope value

• By moving vertically by the slope value

If the slope is 7, how many units do you rise and run to plot the next point?

• Rise 7, run 1

• Rise 1, run 1

• Rise 1, run 7

• Rise 7, run 7
