Exploring Algebraic Manipulation of Linear Functions

The video tutorial covers algebraic manipulation of linear functions, including finding equations in point-slope, slope-intercept, and standard forms. It explains graphing techniques for linear equations and applies these concepts to solve real-world problems, such as calculating costs and analyzing race data. The tutorial emphasizes understanding graph features like intercepts and slopes.

What is the point-slope form of a line passing through the points (7, 4) and (3, -4)?

• y + 4 = -2(x + 7)

• y - 4 = -2(x - 7)

• y + 4 = 2(x + 7)

• y - 4 = 2(x - 7)

What is the slope-intercept form of the line with the equation y - 4 = 2(x - 7)?

• y = -2x - 10

• y = 2x + 10

• y = 2x - 10

• y = -2x + 10

What is the standard form of the line with the equation y = 2x - 10?

• -2x + y = -10

• 2x - y = 10

• -2x - y = 10

• 2x + y = -10

To graph the equation y = 2/3x - 2, where do you start?

• At the origin

• At the y-intercept of 2

• At the y-intercept of -2

• At the x-intercept of 2
