A.  x = 1 , y = -2.

B. They will intersect at the point (1, -2).

Step-by-step explanation:

A.

y = 3x - 5

y = 6x - 8    We simply subtract the second equation from the first. This eliminates y:

0 = 3x - 6x - 5 - (-8)

0 = -3x - 5 + 8

3x = 3

x = 1

Now substitute for x in first equation:

y = 3(1) - 5

y = -2.

B.  x = 1 and y = -2  are the values that satisfy both equations. So the liones will intersect at this point (1, -2).
