Answer: Where are the angles??
Step-by-step explanation:
Answer:
y = (1/2)x - 3
Step-by-step explanation:
The slope of line WX is -2. Therefore, the slope of a line perpendicular to line WX is the negative reciprocal of -2, or +1/2.
Substitute -2 for y, -1 for x and 1/2 for m in y = mx + b, for the purpose of finding b:
-2 = (1/2)(-1) + b. Multiply all terms by 2 to eliminate the fraction:
-4 = -1 + b. Then b = -3, and the desired equation is y = (1/2)x - 3.
