Explain what the slope and intercept mean in the situation. The graph shows the cost in dollars, y, of a muffin delivery and the number of muffins, x, ordered. The slope of the line is 2 and the y-intercept is 3.

 The slope is the cost per muffin and the intercept of 3 is the delivery charge.

Step-by-step explanation:

I will assume that the graph has total cost in dollars for the y axis and number of muffins on the x axis.  A slope of 2 means that y will increase by 2 for every 1 increase in x.  That means that the price of a single muffin is $2.

The intercept of 3 at x = 0, means that there is an upfront (delivery) charge of $3.  One muffin would cost $2 for the muffin plus $3 for the delivery, for a total of $5.

10 muffins would cost $20 for the muffins plus $3 for the delivery, for a total of $23.

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )
