Solving simple inequalities
graphing by plotting points
A very common way of graphing a line is by plotting each point. To do this, you can do a chart with the x and y coordinates, to then plot these into the coordinate plane and graph the line.A pattern can be found in the chart of the coordinates for the x and y, and these will be the slope, which is how inclined the line is, and how far it will move horizontally and vertically in every plot.

slope formula
slope intercept
Slope intercept method is used in the following form:
y = mx + b In this formula, m represents the coefficient or slope, and b represents the y-intercept. This can be then used to graph a line. To to this, you can first have one of your points be in the y-intercept (which is represented in the 'b' in the formula. Then, use the slope (represented by the 'm') to move the correct amount of spaces in the rise, and the run. After plotting this point, joint them together, and the line should be formed. |

unit reflection
During this unit, the hardest part was to use the new formulas and methods to fins the slope or gradient of a line. Since I already had some knowledge on coordinate planes, the plotting of points, and pair of coordinates was easy for me. But something that was new was learning to draw a line with only having the formula. The factor that I remember the most is the slope intercept formula: y = mx + b. Although this was new, I used it and talked about it so many times that I remembered it perfectly. This unit wasn't a challenge, but there were still many things that I learned in it, and many methods and procedures that will help me.
***REAL LIFE APPLICATION: This skills helped me in other classes, when we were working with graphs for results, or information. I no longer had trouble understanding it, neither figuring out what the slope was (what was the change from one point to the next).
