Slopes of Parallel and Perpendicular Lines

Question 1

Which lines are perpendicular to the line y – 1 = (x+2)? Check all that apply.y + 2 = –3(x – 4)y − 5 = 3(x + 11)y = -3x – y = x – 23x + y = 7

Revolt · Accepted Answer

A: y + 2 = –3(x – 4); C: y = -3x –; E: 3x + y = 7

Question 2

Are the students correct? Explain.

Revolt · Accepted Answer

C: Both students are correct; the slope should be –1, passing through (4, 2) with a y-intercept of 6.

Question 3

What is the slope of the line that is parallel to the given line and passes through the given point? What is the equation, in point-slope form, of the line that is parallel to the given line and passes through the given point? What is the y-intercept of the line that is parallel to the given line and passes through the given point?
