Finding the Equation of a Line with Point-Slope Form

What is the initial step in finding the equation of a line using point-slope form?

• Identifying the x-intercept

• Identifying the slope

• Identifying the y-intercept

• Identifying two points on the line

Which of the following points is used in the example to find the equation of the line?

• (2, 8)

• (-3, 5)

• (0, 0)

• (1, 1)

What is the point-slope form of the equation of a line?

• y = x + b

• y = mx + b

• y - y1 = m(x - x1)

• y = m(x - x1) + b

How is the slope (m) calculated between two points?

• (x2 - x1) / (y2 - y1)

• (y2 - y1) / (x2 - x1)

• (x1 - x2) / (y1 - y2)

• (y1 - y2) / (x1 - x2)
