Answer:
Undefined or Infinity
Step-by-step explanation:
(x1,y1)=(-11,8)
(x2,y2)=(-11,-17)
Slope = (y2-y1)/(x2-x1)
= (-17-8)/(-11-(-11))
= -25/0
= Undefined
Answer:
Step-by-step explanation:
Try dividing the first equation by 3. The result will be identical to the second equation. Thus, we have two lines that coincide, and therefore there are an infinite number of solutions.
Answer:
r=10
Step-by-step explanation:
Answer:
x = 2
Step-by-step explanation:
5x - 2 = 10 - x
<em>Add x to both sides</em>
6x - 2 = 10
<em>Add 2 to both sides</em>
6x = 12
<em>Divide both sides by 6</em>
x = 2
