Equation simplifies to y=3/2x+4, so y-int=4 and slope=3/2 (up 3/right 2)

3 plots --> (-2, 1), (0, 4), (3, 6)

For this case we have the following equation:


y + 2 =(3)/(2) (x + 4)

We can rewrite it in the way


y = mx + b

Where m is the slope and b represents the cut point.

So:


y =(3)/(2)(x + 4) -2


y =(3)/(2)x +(12)/(2)-2


y =(3)/(2)x + 6-2


y =(3)/(2)x + 4


m =(3)/(2)\\b = 4

To graph, we look for two points through which the line passes:

Doing
x = 0 we have:


y =(3)/(2)(0) +4


y = 4

So, we have the point:
(x1, y1) = (0,4)

By doing
y = 0 we have:


0 =(3)/(2)x + 4


-4 =(3)/(2)x


-8 = 3x


x =-(8)/(3)

So, we have the point:
(x2, y2) = (-(8)/(3),0)

We locate
(x1, y1) = (0,4) and
(x2, y2) = (-(8)/(3),0) in a coordinate plane and the graph is attached.
