Choose the equation and the slope of the line that passes through (6,-4) and is parallel to the x-axis.

C and F

Step-by-step explanation:

First the slope.

It says the line is parallel to the X-axis..., so the Y is stable, remains the same all the time, since it never goes closer or farther to the X-axis... so it's an horizontal line.  Thus the slope is 0.

Then the equation

Since the slope is 0, there's no variation on the Y-axis... it has the same Y value all along.  Only the first two equations satisfy that (answers B and C).  But we know the line passes through the point (6,-4)... since the Y value of that point is -4... the correct equation is C. y = -4.

i use my brain for prombles like this maybe you could try it

step-by-step explanation:

3

step-by-step explanation:

divide 13.5 by 9 to get the scale factor. it equals 1.5

2 * 1.5 = 3
