Suppose we have four equations of lines as follows: A) y = -x + 1 (ie., y = -1x + 1 is a line with slope -1 (going down) and y-intercept 1) B) y = x – 1 (ie., y = 1x - 1 is a line with slope 1 (going...

Suppose we have four equations of lines as follows:
A) y = -x + 1 (ie., y = -1x + 1 is a line with slope -1 (going down) and y-intercept 1)

B) y = x – 1 (ie., y = 1x - 1 is a line with slope 1 (going up) and y-intercept -1)
C) y = 2x - 1 (ie., y = 2x - 1 is a line with slope 2 (going up) and y-intercept -1)
D) y = -2x + 1 (ie., y = -2x + 1 is a line with slope -2 (going down) and y-intercept 1)

Draw a grapgh to represent each equation.
