Faith is in the business of manufacturing phones. She must pay a daily fixed cost to rent the building and equipment, and also pays a cost per phone produced for materials and labor. The equation C
=
225
p
+
700
C=225p+700 can be used to determine the total cost, in dollars, of producing
p
p phones in a given day. What is the
y
y-intercept of the equation and what is its interpretation in the context of the problem?

Which graph shows a function with a range of all real numbers greater than or equal to -1

Solve for x, y, and z. show all steps.

The data shown in the table below represents the weight, in pounds, of a little girl, recorded each year on her birthday. age (in years) weight (in pounds) 2 32 6 47 7 51 4 40 5 43 3 38 8 60 1 23 part a: create a scatter plot to represent the data shown above. sketch the line of best fit. label at least three specific points on the graph that the line passes through. also include the correct labels on the x-axis and y-axis. part b: algebraically write the equation of the best fit line in slope-intercept form. include all of your calculations in your final answer. part c: use the equation for the line of best fit to approximate the weight of the little girl at an age of 14 years old.
