Exploring X and Y Intercepts in Linear Equations

The video tutorial explains how to find the x- and y-intercepts of the equation 2y + 1/3x = 12. It begins with a refresher on what intercepts are, then demonstrates how to calculate the x-intercept by setting y to 0 and solving for x, resulting in the point (36, 0). Similarly, it finds the y-intercept by setting x to 0 and solving for y, resulting in the point (0, 6). The tutorial concludes by plotting these points on a graph to visualize the intercepts.

What is the x-intercept of the equation 2y + (1/3)x = 12?

• (36, 0)

• (0, 36)

• (12, 0)

• (0, 12)

How do you find the x-intercept of a linear equation?

• Set y to 0 and solve for x

• Set x to 0 and solve for y

• Multiply both sides by x

• Divide both sides by y

If x is 36 when y is 0, what point does this represent on the graph?

• (36, 0)

• (0, 12)

• (12, 0)

• (0, 36)
