Answer:

The slope-intercept form is $y = - \frac{1}{2} x - 4$

Step-by-step explanation:

☆We are going to solve the equation.

☆We are solving for y.

☆All we need to do is divide.

$\frac{2y}{2} = \frac{ - 1x - 8}{2} \\ \\ y = - \frac{1}{2}x - 4$

The equation of a line is y= -1/2x - 2. What is the equation of the line that is perpendicular to the first line and passes thro

Fed [463]

If two line are perpendicular. The multiply of their slopes are equal to -1.
First line's slope is: -1/2x because if the line equation is form of y=ax+b a is slope.
Let say second line's slope is m
m.-1/2=-1 so m=2
y=ax+b is general form of linear function/equation. (a=slope)
y=2x+b
If this line passes through the point (2,-2),if we write -2 to y and 2 to x, the equation becomes true.
-2=4+b
b=-6
Thus,
y=2x-6 is true answer.
