Answer:
Step-by-step explanation:
14.3 + 21.1 + x = 50
35.4 + x = 50
x = 50 - 35.4
x = 14.6 <=== she biked 14.6 miles on the 3rd day

Answer:
m = (70-10)/(70-50) = 3 , slope
Step-by-step explanation:
m =(y2-y1)/(x2-x1) = gradient/ slope
choose any points on the graph for each x that corresponds to the y, 
say choose, where x =50, y =10 (make this x1 and y1)
second step choose, another points to make Y2 and X2
where x=70, y=70, make these , y2 and x2
thus, m = (70-10)/(70-50) = 3
