• 

What is the equation in Point-Slope form

of the line that goes through

the point (6,1) and has a slope of -3?

• y - 6 = -3(x - 1)

• y + 6 = -3(x + 1)

• y - 1 = -3(x - 6)

• y + 1 = -3(x + 3)

Write an equation in slope-intercept form of the line that passes through the given points: (–7, –4) and (–5, –6)

• y = x – 1

• y = –x – 11

• y = –x – 10

• y = x – 10

Convert the standard form equation into slope-intercept form.

6x - 7y = -35

Which two lines are parallel?

Which two lines are perpendicular?

Write the equation of a line PERPENDICULAR to the line y = 3x + 2 that passes through the point (9, -2)

• y = -1/3x - 5

• y = 3x-29

• y = 1/3x -5

• y = -1/3x +1

Write the equation of the line PARALLEL to the line y = 4x - 9 that passes through the point (-2, 4)

• y = 4x + 12

• y = -4x -4

• y = -1/4x + 5/2
