When you reflect a figure across the x axis do the x-coordinates change or remain the same?
When you reflect a figure across the x-axis, the x-coordinates of the points remain the same, while the y-coordinates change sign. This means that if a point is at (x, y), its reflection across the x-axis will be at (x, -y).
What does transformations mean in maths?
A transformation is when a figure moves across the x or y axis on a grid.
How do you reflect y equals 2?
You cannot: you need to know the axis or point of reflection.
How can you reflect figures in the x-axis and y-axis?
For a given coordinate pair. A reflection in the y-axis is making the 'x' term negative. e.g. ( a,b,) ' (-a, b). Similarly for a reflection in the x-axis is making the 'y' term negative. e/.g. ( c,d) ; ( c,-d).
How do you reflect an image over the X-Axis?
change the y value to -y, and bring the negative over the equal sign. example. y=2x^2 reflected on the x-axis looks like y=(2x^2)/-1 which is equal to y=-(2x^2)
an architect transforms?
reflect across the y-axis
What rule describes a transformation across the Y-Axis?
Since the x coordinate will change, but not the y coordinate, take (x,y) and reflect across the y axis and you have (-x,y)
How you can swap the axis of a chart?
Reflect the chart in the line y = x.
How do you reflect over x axis?
You change the value of y to -y. ex: (4,5) reflected over the x-axis is (4,-5)
How do you reflect over the y axis when your x axis is already negative?
The bit with the negative x-axis goes to the positive x-axis.
What does the slope of a budget line reflect?
the price of goods on the x axis in terms of the good on the y axis
How do you reflect a figure across the y axis?
Replace each point with coordinates (x, y) by (-x, y).
What is a rectangular coordinate grid?
a grid in a rectangular shape with a x axis and a y axis.
When you reflect a figure across the x axis do the x-coordinates change or remain the same?
When you reflect a figure across the x-axis, the x-coordinates of the points remain the same, while the y-coordinates change sign. This means that if a point is at (x, y), its reflection across the x-axis will be at (x, -y).
How do you reflect over the y-axis?
count the spaces on your graph until you reach the y axis then start over and count again till you count the same number that you it took you to reach the y axis... sounds kinda confusing.... but good luck !
How to calculate Q first moment of inertia above and below the neutral axis?
-find the area(A) of the shape above the neutral axis (or above a particular point if given) - locate the centroid (y')of the shape relative to the neutral axis(or above point) using y' = ∑AiYi / ∑Ai - first moment of area = A*y' (or y' + distance of given point from neutral axis)
What does transformations mean in maths?
A transformation is when a figure moves across the x or y axis on a grid.
