Answer:
option A. 3x - y = 2 and 3x - y = 1
Step-by-step explanation:
Using the rule of y-intercept which is the value of y when x equals 0
<u>Option A:</u> 3x-y=2 and 3x-y=1
y-intercepts will be ⇒ -2 and -1
<u>Option B:</u> 3x+y=2 and 3x-y=1
y-intercepts will be ⇒ 2 and -1
<u>Option C:</u> 3x-y=2 and 3x+y=1
y-intercepts will be ⇒ -2 and 1
<u>Option D:</u> 3x+y=2 and 3x+y=1
y-intercepts will be ⇒ 2 and 1
Comparing the results with the y-intercepts from the graph
From the graph the system of equation intersects with y-axis, (which mean x=0), at y = -2 , -1
So, the system which is represented by the graph is option A
check the picture below.
since we know all those interior points are midpoints, then those interior lines are midsegments, recall the midsegment is half the parallel base.
in this case, the green DF || AC, and since AC is 50, DF is half that, 50/2.
