A, because 1/4 is your slope of the line. which means you find a point where the line intersects and count 1 up and four over to the right and should end up where the line touches the graph again. if it were to be -1/4 it would be opposite and the line would be going the other way. and 1 would be your y-intercept. this is where the line crosses over the y axis at 1! hope you found this helpful!

Answer:
-1
Step-by-step explanation:
So pretend weekend calls is x and weekday calls are y.
the formulas is x + y = 610
0.07x + 0.08y = 48.05
So, x = 610 - y
Then, substitute x into the second equation.
0.07(610 - y) + 0.08y = 48.05
42.7 - 0.07y + 0.08y = 48.05
0.01y = 5.35
y = 535
Then substitute y into the first equation.
x + 535 = 610
x = 75
Just to be sure, substitute x and y into the second equation.
0.07(75) + 0.08(535) = 48.05
5.25 + 42.80 = 48.05
48.05 = 48.05
So, on weekends, he used 75 minutes.
On weekdays, he used 535 minutes.
The answer is 6 ....you just have to do the steps backwards and it will result faster.
6+5=11
11*2=22
22-6=16
16/2=8
