Answer:

Step-by-step explanation:
A line is perpendicular to another if its slope is the negative reciprocal of the other.
Your lines are in slope intercept form here, y=mx+b, where m is the slope. We can see the given line has slope
. The negative reciprocal of that is
, which is the slope of the third answer choice.
Answer:
x = 4(y + 6)/5
Step-by-step explanation:
2x - y = (3/4)x + 6
2x - (3/4)x = y + 6
(8x - 3x)/4 = y + 6
5x/4 = y + 6
5x = 4(y + 6)
5x = 4y + 24
x = (4y + 24)/5
Therefore, x = 4(y + 6)/5
Answer:
y= -4x

ANSWER
B. 3 ft by 8 ft
EXPLANATION
The area is given as 24 square feet.
This implies that,

The perimeter of the rectangular field is given as 22 feet.
This implies that,

Or

We make w the subject in this last equation and put it inside the first equation.

When we substitute into the first equation we get;


This implies that,



When l=3, w=24
Therefore the dimension is 3 ft by 8 ft
I believe the answer is B
