A line with a slope of 13 passes through the points (3, −1) and (2, k). What is the value of k? −4negative 4

-43-4 thirds

343 fourths

4

Step-by-step explanation:

13 = (k - (-1)/(2 - 3)

13 = (k+1)/(-1)

-13 = k + 1

-14 = k

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
