1.) graph the points and use a ruler to draw the line that passes through the 2 points. use the designated color to draw
each line.
blue line: (-3, 2)
(0,4)
purple line: (-5, -1)
(5.-5)
orange line: (1, 1)
(2,-2)
notice that line a goes through the points
(-5, 3) and (0,1). line a has the equation:
y=
x+1
notice that line b goes through the points
(-6, -6) and (6,2). line b has the equation:
y = 3x - 2
notice that line c goes through the points
(-2, 4) and (0, -2). line c has the equation:
y = -3x - 2
2.) use the points above to write an equation in slope intercept form for each line.
blue line
purple line
orange line
3.) which colored line is parallel to line a?
4.) which colored line is parallel to line b?
5.) which colored line is parallel to line c?
6.) what do you notice about the slopes of each
pair of equations?
7.) what do you notice about the y-intercepts of each
pair of equations?
