Answer:
Undefined
Explanation:
When a line is vertical like that, the slope is undefined. If it was horizontal, then it would be zero. Positive slopes go in an upward right direction. Negative slopes go in a downward left direction.
To see which is greater or lease didive the top by bottom.
1/3=<span>0.33333333333
4/6=</span><span>0.66666666666
</span><span>1/5=0.2
</span>Now by using the answer to that we can see that it is up like this:
1/5,1/3,4/6
Answer:
1. 
Step-by-step explanation:
Step-by-step explanation:
hope u understand it's just a simple formula
You can multiply the second equation by -2
-5x + y = 15 everything by -2
10x - 2y = -30
now you can solve them
2x + 2y = -6
10x - 2y = -30
y cancels
2x= -6
10x = -30
12x = -36
/12. /12
x = -3
now to solve for y you substitute x for -3
-5(-3) + y = 15
15 + y = 15
-15 -15
y= 0
