Rewrite equation in slope intercept form, if necessary. Then determine whether the lines are parallel. Explain. 23. Y = -x + 6 24. Y - 7x = 6 25. 3x + 4y = 12 26. 2x + 5y = -1 x + y = 20 y + 7x = 8 6x + 2 = 6 10y = -4x - 20

Step-by-step explanation:

Slope intercept form

m=slope

c= intercept

1)  y= -x + 6      

2) y=7x + 6

3) y= -3/4x + + 3

4) y= -2/5x - 1/5

5) y= -x + 20

6) y= -7x + 8

7) y= -3x + 3

8) y= -2/5x -2    

Line 1 and 5 are parallel because both have the same slope of -1

line 4 and 8 are also parallel as the their slopes are -2/5
