At a brick laying contest, each layer of bricks is expected to be of an inch tall. Three contestants recorded the fraction of layers of brick they placed and the time it took them to place the bricks in the table below.

First, determine the number of inches each contestant made by multiplying the fraction of layers by the height of each layer.

Next, determine what fraction of an hour each contestant took to make their fraction of layers by writing each number of minutes as a fraction of 60 minutes.

Last, determine each contestant’s unit rate in inches per hour.

So, Zeke's unit rate was  of an inch per hour.

Melanie's unit rate was  of an inch per hour.

To find out how much greater Zeke's unit rate was than Xavier's unit rate, subtract Xavier's unit rate from Zeke's unit rate.

Therefore, Zeke's unit rate was  of an inch per hour greater than Xavier's unit rate.

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
