¶ … linear equation and a linear inequality be solved in the same way? Explain why. What makes them different? Team B
A linear equation and a linear inequality can be solved the same except for very specific scenarios: one flips the inequality sign whenever multiplying or dividing by a negative (Staples, 2012). What makes them different is that the answer will not be a single number, but a range of numbers.

What are the four steps for solving a problem? Should any other factors be accounted for when solving a problem? Should any factors be accounted for when explaining how to solve a problem? Explain your answer.
The four steps for solving a problem are to: remove grouping symbols, clear fractions, isolate the unknown variable on one side, and check the answer. Removing grouping signals involves combining like terms. Clearing fractions involves finding the lowest common denominator and multiplying by it through the entire equation. Isolating the unknown variable means getting the variable (generally an x) on its own on one side of the equation, generally through a combination of addition, subtraction, multiplication, or division. Finally, one...
What does the slope of this line represent? How is this graph useful? Provide another example for your colleagues to explain. Team B
The slope of the line represented by (x, y) (hours, feet) would be the rise (change in y) over the run (change in x). Therefore, the line would represent the change in feet over the change in hours. Feet over hours represents the speed of the person walking in terms of feet per hour. Another example would be to represent as y the calories burned in Kcal a person burns per x minute of a particular aerobic activity.
If a line has no y-intercept, what can you say about the line? What if a line has no x-intercept? Think of a real-life situation where a graph would have no x- or y-intercept. Will what you say about the line always be true in that situation? Team B
If a line has no y-intercept, then the line does not cross the y-axis. It is therefore a vertical line and the equation for the line will be x=some number, but that number will not be zero. If a line has no x-intercept, then the line does not cross the x-axis. It is therefore a horizontal…
