Graphing Linear Equations from Standard Form

The video tutorial from Friendly Math 101 covers graphing linear equations in standard form. It begins with a review of x and y-intercepts, explaining their significance and how they are used in graphing. The tutorial then provides three examples of finding intercepts and graphing linear equations. Each example demonstrates the process of substituting values to find intercepts and plotting them to form a line. The lesson concludes with an invitation for viewers to ask questions and subscribe for more tutorials.

What is the y-value of any x-intercept?

• It can be any value

• It is always negative

• It is always 0

• It is always 1

What are the coordinates of the y-intercept if the x-value is 0?

• (0, y)

• (x, y)

• (x, 0)

• (0, 0)

In the first example, what is the x-intercept of the equation 4x + 2y = 12?

• (0, 3)

• (3, 0)

• (0, 6)

• (6, 0)

In the first example, what is the y-intercept of the equation 4x + 2y = 12?

• (0, 6)

• (3, 0)

• (0, 3)

• (6, 0)

In the second example, what is the x-intercept of the equation 2x - 3y = 6?

• (-2, 0)

• (3, 0)

• (0, 3)

• (0, -2)

In the second example, what is the y-intercept of the equation 2x - 3y = 6?

• (-2, 0)

• (3, 0)

• (0, 3)

• (0, -2)

In the third example, what is the x-intercept of the equation 3x - 6y = -12?

• (2, 0)

• (0, 2)

• (0, -4)

• (-4, 0)

In the third example, what is the y-intercept of the equation 3x - 6y = -12?

• (0, -4)

• (-4, 0)

• (2, 0)

• (0, 2)

What is the general form of a linear equation in standard form?

• Ax + By = 0

• Ax - By = C

• Ax + By = C

• Ax - By = 0
