What is the image of (-4, -7) over the x-axis?

Step-by-step explanation:

Any coordinate pair (x,y) reflect over the x-axis becomes (x, -y). That means, the "x" coordinate remains the same and the "y" coordinate flips (negative becomes positive and vice versa).

We are given the coordinates (-4,-7). We know this point gets flipped over the x-axis. This will mean that the "x" coordinate ( x = -4) will remain same BUT the y-coordinate (y = -7) will get "negated". So it will become:

y = -7

y = -(-7)

y = 7

Hence, the final coordinates would be:

(-4,7)

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
