1. Y=mx+b means, y=dependent variable,x=dependent variable, m=coefficient of x, which is how many times you multiply x by, and b= the y intercept which is the upfront cost. So i know the equation is sayingthe dependent variable =the coefficient of x times the independent variable + the y intercept.

2a. A table can be used to see if a relationship is linear if the x and y go up at a steady rate. A graph can be used to see if a relationship is linear by seeing if the line goes up without any curves, bumps, changes, etc. then it is linear.

2b. I have used an equation to solve a problem when for example how much it will cost to rent a bike in the city. If the equation was C=15+5n C= total cost

N= number of hours

then I know it will cost me $15 down payment and $5 per hour.
