This video tutorial reviews conic sections, including parabolas, circles, ellipses, and hyperbolas. It covers key formulas such as the distance and midpoint formulas, and explains how to graph each conic type. The tutorial also discusses the properties of conics, including focus, directrix, and asymptotes, and demonstrates how to classify conics and solve systems of equations involving them.

What is the formula for calculating the distance between two points?

• Square root of (x2 - x1)^2 + (y2 - y1)^2

• x2 + x1 + y2 + y1

• x2 - x1 + y2 - y1

• (x2 + x1) / 2, (y2 + y1) / 2

How do you find the midpoint between two points?

• Add the x-coordinates and y-coordinates separately and divide by 2

• Subtract the x-coordinates and y-coordinates separately

• Multiply the x-coordinates and y-coordinates separately

• Divide the x-coordinates and y-coordinates separately

What indicates that a parabola is horizontal?

• Both x and y are squared

• Neither x nor y is squared

• The y is squared

• The x is squared

What is the focus of a parabola with the equation y^2 = 4px?

• (-p, 0)

• (0, p)

• (p, 0)

• (0, -p)

What effect does a small coefficient have on the width of a parabola?

• Makes it narrow

• Makes it taller

• No effect

• Makes it wide

How do you determine the radius of a circle from its equation?

• Multiply the constant term by 2

• Take the square root of the constant term

• Divide the constant term by 2

• Square the constant term

What distinguishes an ellipse from a circle in its equation?

• Different coefficients for x^2 and y^2

• Only x is squared

• Only y is squared

• Both x and y are squared with the same coefficient

What is a key feature of hyperbolas in their equations?

• Only y is squared

• Only x is squared

• A minus sign between x^2 and y^2

• A plus sign between x^2 and y^2

How can you classify a conic section using its equation?

• By the constant term

• By the presence of a plus or minus sign between terms

• By the coefficients of x and y

• By checking if x and y are both squared

What is the first step in solving a system of conic equations?

• Graph both equations

• Add the equations together

• Subtract one equation from the other

• Substitute one equation into the other
