Given the graph of a scatterplot and a trend line, explain how you would find the equation of the trend line.

first of all, the trend line will be in the form of y = mx + c. ( where m = gradient of a line and c = y-intercept. )

secondly, extend the trend line to touch the y-axis and then read the value of where the line intersects the y-axis. from this you'll get the value of c.

finally take two coordinates from the

trend line and use the gradient formula. this will be the answer for getting m.

Option c. The quantity of gasoline supplied at each price will change.

Step-by-step explanation:

There is a close correlation between the demand and supply. In simple terms, the demand increases inversely to the supply. This causes the price of the goods and commodities to shift. The precise term is inflation - the increase in the price of goods due to the decrease in the supply and increase in demand.
