Question

If the slope of the line joining the points $(3,4)$ and $(-2,a)$ is equal to $-\frac{2}{5}$, then the value of $a$ is equal to

• A. 6
• B. 4
• C. 3
• D. 2
• E. 1

Answer 1

Answer: (A)

According to the given conditions
$\frac{a-4}{-2-3}=-\frac{2}{5}$
$\frac{a-4}{-5}=-\frac{2}{5}$
$a-4=2\Rightarrow a=6$
