According to his training schedule, Hector should plan to run 8 miles during week 1. By week 12,he plans to run 27 miles. How many more miles does hector need to run during week 12 thn week 1?

19

Step-by-step explanation:

because

8miles=1 week

27miles=12 week

=27-8

=19

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)
