You research the average cost of a tank of gasoline for a certain type of car for several recent years to look for trends. The t
able shows your data. What is the equation for a line of best fit? How much would you expect to pay for a tank of gas in the year 2019?
Note: The table below shows the average cost for one tank of gasoline, not one gallon.
y = 1.006x + 26.40; $47.52
y = 1.006x + 26.40; $58.92
y = 26.40x + 1.006; $47.52
y = 26.40x + 1.006; $58.92

When graphing, its how much you rise and run
thats the formula when u have a graph and the question is asking for the slope.
you chose a point, and go down or up however many times it goes to the next point, and you run to the left however many times it gets you to get to that point.
if the line goes downward the slope is therefore negative, and if the line goes upward, the slope is therefore, positive.
m in math is meant to be slope, so
