For two lines to be perpendicular, their slopes must be negative reciprocals of one another, mathematically:
m1*m2=-1, in this case our reference line has a slope of -3 so:
-3m=-1 divide both sides by -3
m=-1/-3
m=1/3
So the perpendicular line will have a slope of 1/3
Hope this helps :) If you have a doubt just comment :)
Answer:
B.
Step-by-step explanation:
because they have the same base and it's a multiplication so you have to add the exponents
X-5.1 = -7.6
+5.1 +5.1
X= -2.5
