Can anyone help me please? (I already posted this once but I forgot the picture)

Constant of Proportionality = 12

Explanation:

x = number of swimmers

y = number of laps

k = constant of proportionality

k = y/x

Use any row to find that k = 12

The direct proportion equation in the form y = kx turns into y = 12x. This means the number of laps is 12 times that of the number of swimmers. Put another way, each swimmer did 12 laps.

-14 is the answer

hope this : ))

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?
