8 A team of workers deliver identical fridges. The team will use the average time to fully load an old lorry to predict the time to fully
load a now lorry.
The table shows the times it took to fully load the old forry with 24 tiedigen.
Time

(mins)
80 55 59 54 63 56
The diagram shows the space available for fridges in the new lorry.
The space is in the shape of a cuboid.
2400 mm
13600 mm
Each fridge needs a rectangular floor space 1000 mm by 800 mm.
The team do not stack fridges.
They think it will take less than 90 minutes to fully load the new lorry.
Are they correct?

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?

(-5,-28)

i graphed to on desmos.

step-by-step explanation:

there are 36 inches in a yard

25 : 36 = 0.69 yards (you can round to 0.70)

if you was gonna solve for a, a is a   < -12
