The answer would be 93.8667 feet per second.
64 miles to feet is 337,920
1 hour = 3600 seconds.
337,920 ÷ 3600 = 93.8667
point slope form:y-2=4(x+1)
then distribute 4 and simplify y-2=4x+4 , y=4x+6 is the slope -y intercept form
then, move 4x on the left side, you get -4x+y=6 , multiply every term by -1, you get 4x-y=-6 which is standard form.
