Mr Chung teaches a 1-hour math class 6 minutes are used for attendance and turning in homework and then he teaches for 18 minutes for the rest of the class the students work on problems for each problem the students spend 3 minutes working on it then with their strong takes 6 minutes to explain it after the class complete four problems all of the class time is used up right and evaluate an expression to show this.​

33 minutes=6+18+3+6

Step-by-step explanation:

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?
