Question: If the slope of a line passing through the points A (2,5) and B (x, 3) is 2, then x is equal to
Options:
A) 1
B) 2
C) $ -1 $
D) $ -,2 $
Show Answer
Answer:
Correct Answer: A
Solution:
- $ \because $ Slope $ =\frac{y _2-y _2}{x _2-x _1} $
Then, $ 2=\frac{3-5}{x-2} $
$ \Rightarrow $ $ 2x-4=-2 $
$ \Rightarrow $ $ 2x=2\Rightarrow x=1 $
