The slope of a line is always zero because the line does not move up or down on the y-axis.
Answer:
A
Step-by-step explanation:
perpendicular lines are the negative reciprocals of each other, and a pair of these lines intersects at 90 degrees.
Subtract 76 on both sides:
2401 - 76 = 76 - 2x - 76
2325 = -2x
Divide both sides by -2:
-1162.5 = x
If you square 3, you get 9, and if you "take the square root of 9", you get 3
