which system is represented by the graphA. 3x-y=2 and 3x-y=1B. 3x+y=2 and 3x-y=1C. 3x-y=2 and 3x+y=1D. 3x+y=2 and 3x+y=1

Answer:option A. 3x - y = 2 and 3x - y = 1Step-by-step explanation:Using the rule of y-intercept which is the value of y when x equals 0Option A: 3x-y=2 and 3x-y=1y-intercepts will be ⇒ -2 and -1Option B: 3x+y=2 and 3x-y=1y-intercepts will be ⇒ 2 and -1Option C: 3x-y=2 and 3x+y=1y-intercepts will be ⇒ -2 and 1Option D: 3x+y=2 and 3x+y=1y-intercepts will be ⇒ 2 and 1Comparing the results with the y-intercepts from the graphFrom the graph the system of equation intersects with y-axis, (which mean x=0), at y = -2 , -1So, the system which is represented by the graph is option A
