Finding Intercepts in Graphing Lines

The video tutorial explains how to graph linear equations using x and y intercepts. It begins by defining intercepts and demonstrates how to find them by setting the opposite variable to zero. Two examples are provided: graphing the equations 4y - 6x = 24 and y = -2x + 3. The tutorial concludes with a summary of the process and encourages practice.

What is the x-intercept of a line?

• The point where the line does not cross any axis

• The point where the line crosses both axes

• The point where the line crosses the x-axis

• The point where the line crosses the y-axis

How do you find the x-intercept of a line?

• Set both x and y to 0

• Set y to 0 and solve for x

• Set x to 1 and solve for y

• Set x to 0 and solve for y

What is the y-intercept of a line?

• The point where the line does not cross any axis

• The point where the line crosses the x-axis

• The point where the line crosses the y-axis

• The point where the line crosses both axes

How do you find the y-intercept of a line?

• Set x to 0 and solve for y

• Set y to 0 and solve for x

• Set both x and y to 0

• Set y to 1 and solve for x
