Given the equations in point slope form, do the equations form parallel lines? y - 2 = 4(x + 1) and y - 2 = 4(x + 6)

• Yes, they are parallel

• No, they are not parallel

A second linear equation is graphed next to the equation y = 5x + 10. Which of the following could represent the slope and y-intercept of the line if the 2 lines are parallel?

• m = 10, y-int: (0, 5)

• m = 5, y-int: (0, 10)

• m = 5, y-int: (0, 4)

• m = 2, y-int: (0, 5)

Which of the following is an equation of a line in point slope form, with a slope of -5 that goes through the point (2, -3)?

• y - 2 = -5(x - 3)

• y + 3 = -5(x - 2)

• y - 3 = -5(x + 2)

• y - 5 = 2(x + 3)

Given the equation in point slope form, y - 1 = 3(x + 2), which of the following represents the slope and a point on the line.

• m = 3;  (-2, 1)

• m = 1;  (3, 2)

• m = 3;  (2, 1)

• m = 3;  (-2, -1)

Which set of equations does NOT represent a set of parallel lines? HINT: solve for y where necessary

• y = 2x + 42x - y = 6
  

• y - 3 = 4(x + 3)y = 3x - 2
  

• y - 2 = 6(x + 2)3x + y = 12
