Y=Mx+b

Slope/M= -1
X= 3
Y= -1

-1 = -1(3)+b

-1 = -3 + b

Add +3 to -3 and -1 to cancel -3 out to get (b)

-3+3 = 0 cancel it

-1 +3 = 2

So, b = 2

In an equation it will be written as

y= -1x + 2

In standard form it will be

1x + y = 2

But your official answer will be

B= 2
Y= -1x+2

X and Z equal 72
Y equals 108.

This is because y and 108° are vertex angles meaning they are both equal to each other. X is 72 because it’s form a supplementary angle with 108°. So what I did to find x is I subtracted 108 from 180 to get 72°. Then I know x and z are vertex angles meaning that z is also equal to 72°
