Question

The fastest recorded lava flow moved at an average speed of 7 miles per hour. The function y = 7xdescribes the distance y the lava moved on average in x hours. Graph the function. Use the graph toestimate how many miles the lava moved after 6.5 hours.50y45403530252015105001234578910y =7x2

Answer 1

y =7x

We have to graph the function:

For that we have to give values to x and get y values:

For example:

x=0 ; y= 7(0) = y=0

So, we have the point (0,0)

For x =6.5

Y= 7 (6.5) = 45.5
