Answer:

A. -2

B. -10

Step-by-step explanation:

Given the equation of the line

$y=\dfrac{1}{2}x-1$

Its slope is $\frac{1}{2}.$

A. Perpendicular line has the slope m, for which

$\dfrac{1}{2}\cdot m=-1\Rightarrow m=-2$

B. The equation of the perpendicular line will be in the form

$y=-2x+b$

This line passes through the point (-6,2), substitute its coordinates into the equation:

$2=-2\cdot (-6)+b\\ \\2=12+b\\ \\b=2-12\\ \\b=-10$

So, y-intecept is -10.
