Answer:
-27/5 or -5 2/5
Step-by-step explanation:
Simplify
1 2/7 to 9/7
-4 1/5 to -21/5
multiply together
(9)(-21)/(7)(5)
-189/35
u can simplify by diving by 5 to get
-27/5
It would be the last graph because at the x-intercept, it crosses the 5
Oh goodness i have no clue
Remember that parallel lines have the same slope.
y=3/7x+11 (in slope intercept form already)
-3x+7y=13 (standard form)
Add 3x to both sides, giving you 7y=3x+13, divide by 7 on both sides, giving
y=3/7x+13/7
Since both equations' slopes' are the same, their graphs will be parallel.
