How can you reflect figures in the x-axis and y-axis?
For reflection in the x-axis, change the sign of the y-coordinate of every point.For reflection in the y-axis, change the sign of the x-coordinate of every point.
Where would you position a triangle on a coordinate plane if you wanted to find the area of the triangle?
Position its base on the x axis in order to find its perpendicular height by means of the y axis.
How do you reflect y equals 2?
You cannot: you need to know the axis or point of reflection.
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)
What change would you need to make to your equation to reflect your graph across the y-axis?
Replace x by -x.
Fazel says that if you reflect a triangle in the x axis and then in the y axis the image of the triangle will be the same as if you did the reflections in the opposite order do you think he is right?
Yes.
an architect transforms?
reflect across the y-axis
How do you reflect over x axis when y is negative?
When you reflect around the x-axis, the sign of every y-coordinate changes.If the point started out above the x-axis, it flips under ... positive 'y' becomes negative.If it started out under the x-axis, it flips above ... negative 'y' becomes positive.
How can you reflect figures in the x-axis and y-axis?
For reflection in the x-axis, change the sign of the y-coordinate of every point.For reflection in the y-axis, change the sign of the x-coordinate of every point.
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 the y axis when your x axis is already negative?
The bit with the negative x-axis goes to the positive x-axis.
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)
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).
How do you reflect over the x axis when a point is over the x axis already?
To reflect a point in the x axis, multiply it's y coordinate by -1. Example: (x, y) over the x axis is now (x, -y), If you come across the y already being a negative, then make it a positive, (x, -y) = (x, y). The x stays the same, and vice versa over the y axis. Hope I helped. I am also having trouble with this, though, What if there is a zero? (5,0), it can't be (5, -0) can it?
What is impedance triangle?
An impedance triangle has resistance (always positive) in the x axis and reactance (at a right angle to resistance) in the y axis. The line that completes this triangle (the hypotenuse) is the absolute value of the impedance.
