Each polio vaccination consists of
4
44 doses, and each measles vaccination consists of
2
22 doses. Last year, Dr. Potter gave a total of
60
6060 vaccinations that consisted of a total of
184
184184 doses.
How many polio vaccinations and how many measles vaccinations did Dr. Potter give last year?

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?

a)(x-2)^2+(y-1)^2=9
