Answer:
<em>C) 180 degree rotation </em>
Step-by-step explanation:
While reflecting a point, with coordinates as (x, y), over x axis the new co-ordinates become (x, -y)
⇒(x, y) → (x, -y)
While reflecting a point, with coordinates as (x, y), over y axis the new co-ordinates become (-x, y)
⇒(x, y) → (-x, y)
So, when these two operations are combined, they the rule followed is,
⇒(x, y) → (-x, -y)
We also know that while rotating a point, with coordinates as (x, y), 180° the new co-ordinates become (-x, -y)
⇒(x, y) → (-x, -y)
Therefore, reflecting a point over x axis and then over y axis will yield the same result as rotating a point 180°.
In "slope-intercept form"
y = mx +b
the value "m" is called the slope, and the value "b" is called the intercept.
There is another form for the equation of a line, called "point-slope form".
y = m(x -h) +k
where m is still the slope and (h, k) correspond to the (x, y) of the point.
If you write the equation of your line in this "point-slope form", it is easily manipulated to be in the "slope-intercept form".
Fill in
m = (-3/5)
h = -4
k = 0
y = (-3/5)(x -(-4)) +0
Now, you simplify this by using the distributive property.
y = (-3/5)x -(3/5)*4
y = (-3/5)x -12/5 . . . . . . . . . the desired equation

Your understanding of math improves immensely when you become familiar with the terminology. A lot of the rest of it is pattern matching--identifying the parts of one expression that correspond to the parts of another one.
(You will see another version of the "point-slope form", but I find this one the easiest to use for manipulating the equation to other forms.)
