-3x -8y = -23
4(7x + 2y = -13)
-3x -8y = -23
28x + 8y = -52
25x = -75
x = -3
-3(-3) - 8y = -23
9 - 8y =-23
32 = 8y
y=4
The answer is B.red
the reason:
if x=2
-2 (2)+ 5y = 10
-4 +5y = 10
5y = 10+4
5y = 14
y = 2.8
now we have the point (2 . 2.8) which is absolutely on the line -2x + 5y = 10
when we look for it we see that it's on the line b which means line b is -2x + 5y = 10

Step-by-step explanation:
Page 1:
I'm not sure about the first page but here is what I think.
Increased by a value of 3.
Figure 0, is most likely 2 blocks.
Starting value = 2
Growth = 3
y= 3x + 2
Fill in the values to get y.
For example, 3(52) + 2
The rate of change is 3
The y - intercept is 2
The equation of the line is y= 3x + 2
Page 2:
I assuming that the y-intercept is -5 considering it is with 0.
Looking at 10 I see 25. What times 10, subtracted by 5 will get you 25?
3
So I assume that the equation is 3x - 5. Apply this equation to 6 and 0 to see if it is correct.
3(6) - 5 = 13. Now apply this to the other values to get the rest of the chart.
Not sure what the x means in the last input
Red Line
<em>Slope:</em> 3

Blue Line
<em>Slope: </em> (-1/3)
<em>y-intercept: </em>-4
<em>Equation: </em>y = (-1/3) - 4
