Please help!! I need the answer and the explanation on how to do this

the first one

Step-by-step explanation:

y=3x+2

2x+y=-4

becomes

3x+2=y

2x+4=-y

add them

5x+6=0

5x=-6

x=-5/6

take x and replace it for one equation

y=-8/5

So,

in this case, the easiest way to graph the line is to test two (2) easy values, find two (2) ordered pairs, locate them on the coordinate grid, and draw a line through those points.

an obviously easy x-value would be -4.  this would make the right side equal zero:
y + 2 = 32(-4 + 4)
y + 2 = 32(0)
y + 2 = 0
y = -2

ordered pair: (-4, -2)

another easy one would be x = -3.
y + 2 = 32(-3 + 4)
y + 2 = 32(1)
y + 2 = 32
y = 30

ordered pair: (-3, 30)
first ordered pair: (-4, -2)

now, just plot those points on the graph and you will have the line that represents y + 2 = 32(x + 4).
