Answer:

Step-by-step explanation:

2x + 3y = -12

-x - 3y = 18

x = 6

-6 - 3y = 18

-3y = 24

y = -8

(6, -8)

<h3>Line equation of g :    y  = 1 x  + a</h3><h3>Line equation of h :    y  = 1 x  + b</h3><h3>Line equation of k :    y  = 1 x  + c</h3>

Step-by-step explanation:

Here, given:

The lines g, h and k are given to be parallel.

Also, each of the line has a  slope  = 1

Now, as <u>graph is missing</u>.

Using the needed graph, find the y - intercepts ( a point where x = 0) in the graphs.

Let us assume, the y intercept for  g = a

Let us assume, the y intercept for  h = b

Let us assume, the y intercept for  k = c

Now, by SLOPE INTERCEPT form:  y = m x  +  C  : m = slope. C- y intercept

So, the equation of these three lines is given as:

Line equation of g :    y  = 1 x  + a

Line equation of h :    y  = 1 x  + b

Line equation of k :    y  = 1 x  + c
