Evaluating Linear Functions and T-Charts

Charlie introduces T-charts as a tool for finding values in equations. He demonstrates using a simple equation, y = x + 2, to show how T-charts can help identify patterns and graph lines. The video covers plugging in values for x, calculating corresponding y values, and using these ordered pairs to graph a line.

What is a T-Chart primarily used for?

• To memorize multiplication tables

• To find values in an equation

• To draw geometric shapes

• To solve word problems

In the equation y = x + 2, what does the '2' represent?

• The y-intercept

• The slope of the line

• The x-intercept

• The variable

What is the first step in using a T-Chart for an equation?

• Choose a value for x

• Graph the equation

• Solve for y

• Find the slope

What does the equation y = x + 2 represent?

• A constant equation

• A cubic equation

• A linear equation

• A quadratic equation

If x = 0 in the equation y = x + 2, what is the value of y?

• 3

• 2

• 1

What is the value of y when x = 1 in the equation y = x + 2?

• 3

• 1

• 2

• 4

When x = 2, what is the corresponding y value in the equation y = x + 2?

• 3

• 5

What happens to the value of y as x increases in the equation y = x + 2?

• y decreases

• y becomes negative

• y increases

• y remains the same
