Answer:
y = 8x
Step-by-step explanation:
a y = 8x
40 = 8*5
40 = 40
This is a solution
Slope is a number that represents how much the y-value changes over a certain span of x-values. However, since y is a constant set to 3, the y-value never changes, meaning the slope is 0.
The slope will always be 0 for any equation that has the form:
You could also choose two random points and solve for the slope. Let's take (0,3) and (1,3).
You can verify these are actual points on the line since the y-value is 3.
Now, let's calculate for slope:
The slope is indeed 0 as shown from this.
Let me know if you need any clarifications, thanks!

Writing and solving an equation of ratios is the way to go here. See if you can figure out why the following is correct:
x+3 x
----- = -------
12 x+3
Then (x+3)^2 = 12x, and x^2 + 6x + 9 = 12x, so that x^2 - 6x + 9 = 0
This is the square of (x - 3). Thus, x-3 = 0, and x = 3.
The value of x is 3.
Answer- 180 degree rotation.
Basically how I remember it is by 90 degree clockwise is switch x,y and change the sign of the x—> y,-x. 90 degree counterclockwise is switch x,y and change the sign of the y —> -y, x. 180 degree is changing both signs with no switch. 360 stays the same.
