Answer:
d Dilation by a scale factor of 2 followed by reflection about the y-axis
Step-by-step explanation:
In each case, the transformation is ...
(x, y) ⇒ (-2x, 2y)
So, a dilation by a factor of 2 is involved. That is what multiplies the coordinates by 2. Reflection in the y-axis is what negates the x-coordinate.
The transformations are ...
Dilation by a scale factor of 2 followed by reflection about the y-axis
Answer: I'm not going to give out the answers but I'm happy to explain it and help you out if you're still confused. I'm a geometry honors student rn btw just so you know my credentials.
Step-by-step explanation:
To find slope and write it in slope-intercept form you first need to know the equation and what different variables represent.
y = mx + b is the equation for slope-intercept. You need to find what m and b are to right a slope-intercept equation. for example the first problem's answer is y =
x + 1
m is slope which is the angle that the line is at. To find slope or m, you need to choose a point on the graph. Then, count the amount of spaces vertically and horizontally until the next point on the graph. When I say point, I'm referring to a place on the graph where the line cross perfectly over the intersection of two lines on the graph. Slope is always 'rise over run' meaning it is a fraction containing the amount up or down, over the amount left or right. For example, the first problem (the one on the top left) the slope is
.
b is the y-intercept. The y intercept where the line crosses the y-axis which is that bold line going up and down in the middle. For example in number one, the y-intercept is 1 because it is one unit up from the origin. (the origin is 0,0, or the very middle of the graph).
Hope this helps! :)
Answer:
i want to say that the answer is D but in reality you cant have a negative number in the square root and then take it out unless is tied to the exponent, but the most likey answer would be D since there are no other answer choices
