Learn how to determine if a point lies on a graph using standard form of a quadratic

The video tutorial covers how to determine if a point lies on a line by plugging in coordinates into the line equation. It includes an example problem involving fractions and discusses finding the axis of symmetry in standard form. The teacher also touches on vertex form and the importance of checking points, although some points do not work in the given example.

How can you verify if a point is on a line?

• By drawing a perpendicular from the point to the line

• By plugging the point's coordinates into the line's equation

• By checking if the point is at the origin

• By ensuring the point is equidistant from the line

What is the first step in subtracting a whole number from a fraction?

• Rewrite the whole number as a fraction

• Convert the fraction to a decimal

• Multiply the fraction by the whole number

• Add the whole number to the fraction

When subtracting fractions, why is it necessary to find a common denominator?

• To convert fractions to whole numbers

• To ensure the fractions are equivalent

• To make the subtraction process possible

• To simplify the fractions

What is the formula to find the axis of symmetry in standard form?

• X = b/2a

• X = -a/2b

• X = -b/2a

• X = a/2b

What should you do after finding the axis of symmetry to locate the vertex?

• Use the axis of symmetry as the vertex

• Plug the axis of symmetry value into the equation

• Draw a line parallel to the axis of symmetry

• Multiply the axis of symmetry by the coefficient of x
