Answer:
Step-by-step explanation:
Perpendicular bisector passes through the midpoint of the line.
<u>The midpoint is:</u>
- x = (10 - 10)/2 = 0
- y = (-15 + 25)/2 = 5
<u>Slope of the line:</u>
- m = (25 - (-15))/(-10 - 10) = -2
The line perpendicular to this has to have a slope of 1/2 as perpendicular lines have opposite-reciprocal slopes.
<u>Use point-slope form and point (0, 5) to find the equation of the line:</u>
- y - 5 = 1/2(x - 0)
- y = 1/2x + 5
Correct option seem B as others don't match ours
Answer:
-10
Step-by-step explanation
You subtract 4 by 4 which is zero. then you subtract 2 making it -2. You multiple 5 by -2. X is equal to -10.
Answer:
When rotating a point 270 degrees counterclockwise about the origin our point A(x,y) becomes A'(y,-x). This means, we switch x and y and make x negative.
