A line is perpendicular to y = 2x - 7 and goes through (3, 5).

What is the equation of this line?

Use point slope format as your answer

• y + 5 = -1/2(x + 3)

• y - 5 = 1/2(x - 3)

• y - 5 = -1/2(x - 3)

• y - 5 = -2(x - 3)

What is the slope of a line parallel to the line whose equation is: -2x + y = - 7?

• -2

• 1/2

• -1/2

• 2

When asked to write the equation of a line parallel to another you must...

• Use the same slope as the line that is parallel to it

• Use an opposite slope of the line it is parallel to

When asked to write the equation of a line perpendicular to another you must...

• flip the fraction

• change the sign

• flip the fraction and change the sign

Write an equation of a line that passes through the point (5,-1) and is parallel to the line y = (-3/5)x -3

• y = (-3/5)x + 2

• y = (-3/5)x -2

• y = (-3/5)x + 6

• y = (5/3) + 2
