Math Reflection 2

1. The equation y= mx + b is a linear relationship.

y is the dependent vairable and the output. For example, y could be the distance that someone could walk in 10 seconds.
m is the rate. For example, Henri's rate for walking is 1 meter per second.
x is the independent variable and input. For example, x could be the time that someone could walk in 1 mile.
b is the y-intercept. For example, b could be a head start in a race.


2a. A table or graph for a linear relationship can be used to solve a problem. For a table, you would look at the x and y columns and find the relationships. Then you would change the variables and solve the problem.
b. I have used an equation to solve a problem by substituting the variables with the information that I have, and then solve. Equations can also be used to check if the answer to a problem is correct by putting the answer on one side and putting the problem on the other and then solve.
