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.

Answer:
g(9) = 48
Step-by-step explanation:
g(x)= – x2–5x + 12
<u>I'll assume this is </u>
<u>g(x)= – x^2–5x + 12</u>
find g(9)
find g(9)
g(9)= – 9^2–5(9) + 12
g(9)= 81–45 + 12
g(9) = 48
Answer:
The slope of a line characterizes the direction of a line. To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points .
