Point b, located at (-4, -7), is reflected over the y-axis. what are the coordinates of b'? (-4, 7) (4, -7) (4, 7) (-4, -7)

(4, -7)

Step-by-step explanation:

The rule for a reflection over the y-axis is (x,y)→(−x,y). So (-4, -7)=(--4, -7) since the 2 negatives cancel out the new coordinates are (4, -7)

mxb67

step-by-step explanation:

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:
