Make sure to focus on the arms and feet of the man.
it’s my final
set for 100 points !

Shoes= 10

Man= 5

Tie= 4

So, 10+5*4= 30 <— Answer

How to get variables:

Shoes:

3 shoes are equal to 30, so to find the value of the shoes use 3x=30. X=10

Man:

2 men and a shoe is equal to 20. So, 2x+10=20

2x=10

X=5

Tie:

2 ties and a man are 13. So,

2x+5=13

2x=8

X=4

THIS IS VERY EASY...

THE PAIR OF SHOES ARE 10 BECAUSE WITH THE THREE PAIRS, IT ALL ADDS UP AS 30...

IF ONE SHOE IS 10, WE HAVE 10 LEFT IN ORDER TO MEET THE TOTAL OF 20...THEREFORE, THE MAN IS 5 ALSO, IF A MAN IS 5, THEN BOTH MEN WILL BE A TOTAL OF 10 AND SINCE A PAIR OF SHOES IS EQUAL TO 10, THE TOTAL IS SET TO 20...

AS I SAID BEFORE, A MAN IS 5 AND WE HAVE TO KNOW THE AMOUNTS FOR THE TIES (IDK WHAT TO CALL IT... GUESS IT'S TIES...) BUT, WE HAVE TO FIND THE VALUE FOR THE TIE I JUST SOLVED IT AND THE TIE IS 4... WHEREAS, A MAN, AND THE TIES ADD UP TO 13 (5 + 4 + 4)

NOW WE KNOW ALL THE VALUES OF THE OBJECTS... SO WE CAN EASILY SOLVE THIS... SHOES ARE 10, THE MAN IS 5 AND THE TIES ARE 4, THESE ADD UP TO A TOTAL OF 19...

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
