The answer is option c, but if you need an explanation refer to the attachment below -
add the 2 equations together
x+y =9
x-y =7
----------
2x = 16
divide by 2
x=8
x+y =9
substitute in x=8
8+y =9
subtract 8 from each side
y =1
(8,1)

Answer:
Option 2
Step-by-step explanation:
First, find the slope of the line of the graph using the points given as (5, -3) and (13, -9):
Any of the triangle in the options given, whose opp side has the same slope value of -¾, is the triangle we are looking for.
Option 1: slope between the points (0, 2) and (3, -2).
Option 2: slope between the point (-7, 6) and (-3, 3).
Option 2 has the same slope as the one given in the graph. This is the answer.
Option 3: slope between the points (5, -1) and (2, -5).
Option 4: slope between the points (2, -7) and (6, -4).
The answer is Option 2
