18 mL of the 67% solution must she use.
Solution
x = 42 - y
0.67 x + 0.46 y = 0.55 (42)

0.67 (42 - y) + 0.46 y = 23.1
28.14 0.67 y + 0.46 y = 23.1
- 0.21 y = -5.04
y = 24 L

x = 42 - 24
x = 18 L

18x + 2y = –36 in y = mx + b form is y = -9x - 18, where m stands for slope. Therefore, the slope is -9.
To find the y-intercept, let x = 0.
y = -9x - 18;
y = -9(0) - 18;
y = 0 - 18 = -18

Slope: -9
Y-intercept: -18

Are the graphs of the lines in the pair parallel? Explain. y = 4x + 6 7x – y = 7 A. No, since the slopes are different. B. No, since the y-intercepts are different. C. Yes, since the slopes are the same and the y-intercepts are different. D. Yes, since the slopes are the same and the y-intercepts are the same.

No, since the slopes are different.

The slope of the first line (y = 4x + 6) is 4, while the slope of the second line (7x - y = 7) can be determined by rearranging the equation as y = 7x - 7, making its slope 7. Since the slopes are different, the lines are not parallel.
