Linear Equations and Slope Concepts

What is the general form of a linear equation in slope-intercept form?

• y = ax + c

• y = mx + b

• x = my + b

• y + b = mx

How is the slope (m) calculated from two points (x1, y1) and (x2, y2)?

• (y2 - y1) / (x2 - x1)

• (x2 - x1) / (y2 - y1)

• (y1 - x1) / (y2 - x2)

• (x1 + x2) / (y1 + y2)

How can you find the y-intercept (b) from a table of values?

• It is the y-value when x is 1

• It is the x-value when y is 0

• It is the y-value when x is 0

• It is the x-value when y is 1

What is the slope (m) for the first table presented?

• 1

• 2

• 4

• 6

What is the equation of the line in slope-intercept form for the second table presented?

• y = 4x + 10

• y = -4x + 10

• y = 10x - 4

• y = -4x - 10

What is the slope of the line represented by the table?

• 1/3

• -1/3

• 3

• -3
