A quarter back is sacked for a loss of 4 yards. On the next play his team loses 10 yards. Then the team gains 12 yards on the third play. Write an addition expression to represent this situation. Then find the sum and explain its meaning.

see below

Step-by-step explanation:

loss of 4 yards  

-4

loses 10 yards.

-10

gains 12 yards

+12

The expression for the three plays

-4 +(-10) + 12

The sum is

-2

The team needs to gain 10 yards to make a first down and instead they lost 2 yds

The answer is 6

Step-by-step explanation:

4 - 10 = -6  then

the team gains 12 more yards which is

-6 + 12 = 6

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?
