Answer: 7
Step-by-step explanation:
Let us find the slopes of the two lines ax+by=c, slope m1 = -a/b bx-ay=c, slope m2 = b/a m1*m2 = (-a/b)(b/a) = -1 Therefore the two lines are perpendicular so the answer is D
Write it as an equation:
X - 10 = 6x + 3
Now solve for x:
Subtract 3 from both sides:
x-13 = 6x
Subtract 1 x from both sides:
-13 = 5x
Divide both sides by 5:
x = -13/5
