Acell phone company found that 15 of their phones sold in june were defective. the company sold 250 phone in june. how many of the 300 phones sold in july should they expect to be defective?

Write and solve an equation of ratios, as follows:

15 250

= = 10/12.

x 300

Then 15(12) = 10x, and x = 18. The company could well predict that 18 out of the 300 phones it sells in July will be defective, based upon past history.

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
