And Tuan earns money at a steady rate mowing lawns. The points in parentheses (1, 25) and (5,125)appear on a graph of the amount earned versus Number of lawns mowed. What are the coordinates of the point on the graph with an X value of three?

Respuesta :

the answer is (3,75)

the way to find the slope is change in y over change in x... (125-25)/(5-1)
that would simplify to 100/4 which is reduced to 25. So for every lawn he mows, he gets $25. To find out how much he makes mowing 3 lawns, your equation would be y=kx. y=25aka your steady rate time 3aka amount of lawns
so y=25(3)= 75 so for 3 lawns, he gets $75. (3,75)
