How to find the x and y intercepts for a linear equation

The video tutorial explains how to find X and Y intercepts from an equation without graphing. It begins with a review of intercepts, describing the X intercept as the point where the graph crosses the X-axis (Y=0) and the Y intercept as the point where the graph crosses the Y-axis (X=0). The tutorial then provides step-by-step instructions for calculating the X intercept by setting Y to zero and solving for X, and for finding the Y intercept by setting X to zero and solving for Y. Finally, it demonstrates how to use these intercepts to graph the equation.

What is the X value at the Y intercept of a graph?

• 1

• 0

• Y value

• X value

How do you find the X intercept from an equation?

• Set Y to 0 and solve for X

• Set X to 0 and solve for Y

• Set both X and Y to 0

• Graph the equation

What is the X intercept of the equation 3X - 4Y - 6 = 15?

• (0, 7)

• (-7, 0)

• (7, 0)

• (0, -7)

What is the Y intercept of the equation 3X - 4Y - 6 = 15?

• (0, -5.25)

• (5.25, 0)

• (-5.25, 0)

• (0, 5.25)

How can you graph an equation using intercepts?

• Find the slope and plot points

• Plot random points and connect them

• Use a graphing calculator

• Find the X and Y intercepts and draw the line through them
