1)

x =(1/2) y + 5

2x + 3y = -14

2 ((1/2)y +5) + 3y = -14

y +10 + 3y = -14

4y +10 = -14

4y= -24

y=-6

x = (1/2) y+5

x = (1/2)(-6) + 5

x = -3+5

x=2

b. (2, -6)

2.

x+3y = 6

x = 6-3y

4x+6y = -6

4(6-3y)+6y = -6

24 -12y + 6y = -6

24 -6y = -6

-6y = -30

y = 5

x+3y=6

x+3(5) = 6

x+15 = 6

x = -9

a. (-9,5)

3)

y =(1/2) x+ b

it passes through (-6,2)

substitute x=-6 and y=2

2 = (1/2)(-6) + b

2 = -3 + b

b = 5

y = (-1/2) x + 5

a. y=1/2x+5
