Since you already have the equation, all you need to do is pick two values of x.
For example, when x = 0, you get y = 7/4(0) + 2 = 2. So the line passes through the point (0, 2). When x = 4 (picked to cancel the 4 in the fraction), you get y = 7/4(4) + 2 = 9, so the line also passes through the point (4, 9).
You can describe an entire line by any two points that it contains. So plot these two points, then connect the dots with a line passing through them both.

standard deviation of 1 minute, find the probability that a randomly selected college
Speed= distance divided by time so s=d/t
first find the individual speeds during each running segment. we get
s=4.0/32=1/8 km per min
s=2.0/22=1/11 km per minute
s=1.0/16=1/16 km per minute
now we take the average. the person jogged a TOTAL of 7.0 km in a TOTAL 70 minutes. so on average, they jogged 7.0/70=1/10 km per minute
