(1/2)x+b=y because the equation that given the slope is 1/2 if you leave y alone and take the x’s number

put the point now , 4+b=3 so b is -1

the equation is (1/2)x-1=y

Answer:

The small box contains 21 cans

Step-by-step explanation:

Represent the small box with S and the large with L.

For Estelle:

$3L + 5S = 170$

For the boy:

$4L + 4S = 184$

Required

Determine the cans in the small box

$3L + 5S = 170$ --- (1)

$4L + 4S = 184$ --- (2)

Divide (2) through by 4

$L + S = 46$

Make L the subject

$L = 46 -S$

Substitute 46 - S for L in (1)

$3L + 5S = 170$

$3(46 - S) + 5S = 170$

Open bracket

$128 - 3S + 5S = 170$

$128 + 2S = 170$

Collect Like Terms

$2S = 170-128$

$2S = 42$

Divide both sides by 2

$S = 21$

<em>Hence, the small box contains 21 cans</em>
