Steve is mowing lawns for the summer. For every mowing job he charges a $10 service fee then
$5 per hour. Let F represent Steve's fee in dollars) for a single job that took t hours. Create a
linear equation that models Steve's fee.

y=5x+10

Step-by-step explanation:

The slope of the equation is caused by a rate  of change. The only factor changing in this situation is the amount of money he earns per hour, (5 dollars).making 5 your slope. your y intercept is the one time fee (not changing by any increment of time) making 10 your why intercept. Then you just plug those values into the following equation, y=mx+b, where m is your slope and b is your y intercept.

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.
