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 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)
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.

reflect across the y-axis
How do you reflect over x axis when y is negative?
When reflecting a point over the x-axis, you are essentially changing the sign of the y-coordinate while keeping the x-coordinate the same. So, if the original point has coordinates (x, -y), reflecting it over the x-axis would result in the new coordinates being (x, y). This transformation is a fundamental concept in geometry and can be applied to various shapes and figures to create mirror images across the x-axis.
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).
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 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 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.
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.
