The answer is A. A perpendicular equation will have the opposite and reciprocal slope as the original equation.
Once converted to the slope-intercept form of y = mx+b, we find the two equations for A are y = 2x-1 and y = (-1/2)x + 3/2. The opposite reciprocal of the first equation's slope (m in the equation form given) is -1/2, which as you can see if the slope of the other equation.

Step-by-step explanation:
9*10(9) is equal to 810, and 3*10(-4) is equal to -120. This is 6.75 times larger than -120.

Answer:
Yes, y varies directly with x, and the equation is
.
Step-by-step explanation:
To check where there is a direct relationship between x and y, we need to check whether all the x,y pairs we have fit some rule:
.
For the first pair (x=4, y=6.4),

Therefore
.
For the second pair (x=7, y=11.2),

Therefore
.
For the third pair (x=10, y=16),

Therefore
.
For the second pair (x=13, y=20.8),

Therefore
.
So x does directly vary with y, and we have found out that
.
