for the given table the y values always increase by four while the x values increase by one. the at means the slope is 4/1, or 4. the y intercept is where x=0, so it is 4. do the equation of the line is y=4x+4. can't graph it here but that should help you do it.
1 minute for 4 blocks * 24 blocks=6 minutes. this is called dimensional analysis
he would get there faster because his slope is steeper when cycling. here is traveling twice as fast
