Slope, Slope-Intercept Form, Parallel Equation

What are the steps for graphing a line?

• Plot y-intercept
  count slope ratio plot second point
  Draw the line.

• Make a table
  Plot slope
  Draw line

• Plot two points
  Check slope
  Draw line

• Draw line
  Hope it is right

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

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

• m = 3;  (-2, 1)

• m = 1;  (3, 2)

• m = 3;  (2, 1)

• m = 3;  (-2, -1)

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)
