Chapter 4 Review

What is the equation for slope-intercept form?

• y = mx + b

• y = mx - b

• y - y1 = m (x - x1)

• y + y1 = m (x + x1)

What is the equation for point-slope form?

• y = mx + b

• y = mx - b

• y - y1 = m (x - x1)

• y + y1 = m (x + x1)

Write an equation in point-slope form given a slope of 2 and a coordinate point

(1, 4)

• y - 1 = 2 (x - 4)

• y - 4 = 2 (x - 1)

• y + 4 = 2 (x + 1)

• y + 1 = 2 (x + 4)

Write an equation in slope-intercept form given a slope of 2 and a y-intercept of 7.

What is the slope of a line that is parallel to the line: y = -3x + 4

What is the slope of a line that is perpendicular to the line: y = (-1/2)x - 3
