Slope and y-intercept identification:
1.
y = 4x - 1
* Slope (m) = 4
* y-intercept (b) = -1
2.
y = -4x + 0.25
* Slope (m) = -4
* y-intercept (b) = 0.25
3.
y = -9 - 3x (Rewritten as y = -3x - 9)
* Slope (m) = -3
* y-intercept (b) = -9
4.
4x + 2y = 16 (Rewritten in slope-intercept form: y = -2x + 8)
* Slope (m) = -2
* y-intercept (b) = 8
5.
-3x + y = 5 (Rewritten in slope-intercept form: y = 3x + 5)
* Slope (m) = 3
* y-intercept (b) = 5

Graphing instructions:
1.
y = 2x - 3
* Plot the y-intercept (0, -3).
* Use the slope (2/1): From (0, -3), move up 2 units and right 1 unit to plot a second point (1, -1).
* Draw a line through these two points.
2.
y = -4x + 7
* Plot the y-intercept (0, 7).
* Use the slope (-4/1): From (0, 7), move down 4 units and right 1 unit to plot a second point (1, 3).
* Draw a line through these two points.
3.
y = -3x
* Plot the y-intercept (0, 0).
* Use the slope (-3/1): From (0, 0), move down 3 units and right 1 unit to plot a second point (1, -3).
* Draw a line through these two points.
4.
y = x + 6
* Plot the y-intercept (0, 6).
* Use the slope (1/1): From (0, 6), move up 1 unit and right 1 unit to plot a second point (1, 7).
* Draw a line through these two points.
