What is the slope of a line parallel to the line whose equation is y=3x + 4?

The slope of any line parallel to y=3x+4 would be 3!

Step-by-step explanation:

When lines are parallel, they always have the same slope!

When lines are perpendicular, the slope would be the negative reciprocal!

I hope this helps!

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
