A: You are being told to graph the equation y=2x+14 that represents the total amount of money you will spend at the fair in relation to the number of rides you will go on.
B: You can use slope and y-intercept to graph the equation. In this equation, the coefficient of x (2) represents the rate at which the cost increases per ride. This gives you the slope of the line. The y-intercept in this equation is 14, which represents the initial cost when you haven't gone on any rides yet.
C: Using the coordinate plane below, we will graph the equation y=2x+14.

To graph this equation, start by plotting the y-intercept at the point (0,14) on the y-axis. Then, use the slope (2) to find additional points on the line.
For example, when x=1: y=2(1)+14 = 2+14 = 16, so another point on the line is (1,16).
You can continue finding additional points by substituting different values of x into the equation.
Once you have enough points, connect them to form a straight line.
