Please help, just answer this question.

Answer 1

Answer:

$- \frac{5}{2}$

Given that,

Slope of line A=2/5

We know that , slope of perpendicular line is product of slopes.

i.e. M1 • M2=-1

$m1 = \frac{2}{5} \: \:$

m2=?

Now,

$\frac{2}{5} \times m2 = - 1 \\ or \: m2 = - 1 \times \frac{5}{2} \\ \: m2 = - \frac{ 5}{2}$

Therefore, Slope of line B is -5/2.

Hope this helps..
