Answer: &lt;font color=red size=4&gt;y = 15x+50&lt;/font&gt;


Explanation:


The equation is of the form y = mx+b
m = slope = 15
b = y intercept = 50


The slope is the rate of change. It represents how much the cost y goes up each time x increments by 1.
m = 15 tells us that each time we add another session, the cost increases by $15


The y intercept is the starting cost. If you take x = 0 sessions, then you would still pay the up-front cost of $50


Extra info:&lt;ul&gt;&lt;li&gt;The graph is a straight line through the two points (0,50) and (1,65)&lt;/li&gt;&lt;li&gt;You can use Desmos or GeoGebra to graph. Many other options are available as well.&lt;/li&gt;&lt;li&gt;The x intercept is located at approximately (-3.3333, 0)&lt;/li&gt;&lt;li&gt;The y intercept is located at exactly (0,50)&lt;/li&gt;&lt;/ul&gt;
