3x - 2y = -17 -> 9x - 6y = -51

3y - 4x = 24 -> 6y - 8x = 48

9x - 6y = -51

6y - 8x = 48

------------------- +

x = -3

3x - 2y = -17

3(-3) - 2y = -17

-9 - 2y = -17

-2y = -8

y = 4

Coordinate : (-3, 4)

Here are the equations for 4
Kipish [7]

Answer:

Please see attached graph.

Step-by-step explanation:

The equations for straight lines are given as:

i) y = x +4

ii) y= x-4

Yon can form a table for values of x and y that are true for an equation and use these values as coordinates ( x,y ) to plot the graphs and view the lines to select the correct labels for the equations.  

For i)

y= x+4

x       y      coordinates

-3       1          (-3,1 )

-2        2         (-2,2)

-1         3          (-1,3)

0          4         ( 0,4)

1           5          ( 1,5)

2           6         ( 2,6)

3            7         ( 3,7)

Plot the points on a graph tool and draw the line. Do the same for the second equation to view both graphs as shown in the attached graph.
