It takes billy fifteen minutes to complete 1/8 of a recipe. at this rate go long will it take for him to complete the recipe

well, a WHOLE is 1, in this case is 8/8, that'd be a whole.

so Billy does 1/8 in 15 minutes, well, there are 8/8, so do the whole recipe that'd be 8 * 15 minutes, or 120 minutes, or 2 hours.

or you can see it this way, 1/8 is 15 minutes, since there are eight 1/8's, then it'd take 15+15+15+15+15+15+15+15 minutes.

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
