What is the answer to Find the coordinates of the reflection B (4 2) is reflected over the y-axis B and rsquo Question 9 options a) (4 -2) b) (-4 2) c) (-4 -2) d) (4 2) Save?
The answer is b.
M is the midpoint of line segment AB. A has coordinates (3-7) and M has coordinates (-11). What is the coordinates of B?
B is (-5, 9).
If A B C and D are points on a number line B is the midpoint of Ac what is the coordinate?
The 'x' coordinate of B is the average of the 'x' coordinates of A and C. The 'y' coordinate of B is the average of the 'y' coordinates of A and C.

Do all figures with rotational symmetry also have reflection symmetry?
No.For example, a hexagon with equal angles and sides of lengths a,b,a,b,a,b has rotational symmetry of order 3, but it has no reflection symmetry.No.For example, a hexagon with equal angles and sides of lengths a,b,a,b,a,b has rotational symmetry of order 3, but it has no reflection symmetry.No.For example, a hexagon with equal angles and sides of lengths a,b,a,b,a,b has rotational symmetry of order 3, but it has no reflection symmetry.No.For example, a hexagon with equal angles and sides of lengths a,b,a,b,a,b has rotational symmetry of order 3, but it has no reflection symmetry.
If A B C and D are points on a number line B is the midpoint of Ac what is the coordinate?
The 'x' coordinate of B is the average of the 'x' coordinates of A and C. The 'y' coordinate of B is the average of the 'y' coordinates of A and C.
Point (a b) is translated 4 units down. What are the coordinates of the image of (a b)?
They are (a, b-4).
The midpoint of ab is m (-2, -4) if the coordinates of a are (-3, -5) what are the coordinates of B?
The coordinates of point B can be calculated using the midpoint formula. The midpoint formula is used to find the midpoint of two points, and is calculated by taking the average of the x-coordinates and the average of the y-coordinates. In this case, we are given the midpoint of AB, which is (-2, -4). We also know the coordinates of point A, which are (-3, -5). Using the midpoint formula, we can calculate the x-coordinate of point B by taking the average of the x-coordinates of points A and M. This is (-3 + -2)/2 = -2.5. We can calculate the y-coordinate of point B in a similar way. This is (-5 + -4)/2 = -4.5. Therefore, the coordinates of point B are (-2.5, -4.5).
What is The slope of a line is determined by using?
The slope of a line is determined using the coordinates of at least 2 points on the line. If you have 2 points (A, B) and (C, D), the slope of the line can be determined using the formula (B - D) / (A - C) or (D - B) / (C - A) which is essentially the difference of the y-coordinates divided by the difference of the x - coordinates. Alternately, you could think of it as "rise over run", the increase in height (change in y) between the two points over the horizontal distance traveled (change in x).
Describe how to find the coordinates of the image of a point after a 270 degree rotation?
Point A has coordinates (x,y). Point B (Point A rotated 270°) has coordinates (y,-x). Point C (horizontal image of Point B) has coordinates (-y,-x).
When point A has coordinates 65 and the point B has coordinates 2-1 find the coordinates of the midpoint of AB?
oh my goodness not even dr.sheldon cooper can answer that
What are some real life examples of reflection?
Look in a mirror for an example of a reflection. Lift your right hand, and watch your left hand lift in the mirror, or so it appears!In geometry, reflection is a mirror image of a shape, etc.For example: the triangle b is the reflection of triangle a.▲ a▼ b
How do you find the midpoint in a given segment?
If the coordinates of the end points are (a,b) and (c,d) then the midpoint is the point whose coordinates are [(a+c)/2, (b+d)/2]
