Please help me with work

1. the equation is y=mx+b. m= slope and b= y-intercept so your answer should be y=2/3x+2

2. point-slope form is y-y1/x-x1=m answer is y+4=-1(x-1)

3. i give up im sorry my brain is fried ;-;

4.uhh i graphed it and attached an image lol

dang i- cant do no more math today lol sorry good luck

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

idk
