Since this is a linear relationship,the equation will be of the form: y=mx+b, where m=slope and b=y-intercept.
To find a y-intercept, the rule is to set x(no of baloons)=0, then solve. You can see that before any baloons are delivered the cost is $10. This is b, the y-intercept. We now only need the slope, m, to finish the equation. The slope is given as $.50/baloon. Thus, the equation is as follows:
y=.5x+10
see the graph below to illustrate the equation: x=>0
