The equation of the line is C. 1X/2 -2
How you figure this out is you first say when x is zero y is what?
y= 1/2 (0) - 2
You would then see that y=-2 (0,-2)
Plot that point
Next you need to find the slope of the line.
Remember slope is rise over run.
When you 'rise' up one (from -2) and 'run' 2
you are now at the point (2,-1) which is on the line. 
You can continue doing rise/run along the line to check your answer. 
I hope this makes sense! Let me know if you have any questions :)

Find the perimeter of a rectangle with a length of 6x+3 and a width of -2x-5.
blsea [12.9K]
The simple way of calculating a perimeter is to add all of the sides.
For a rectangle this would equal 2 x length + 2 x width
P = 2(6x + 3) + 2(-2x - 5)
= 12x + 6 - 4x - 10
= 8x - 4

At a higher level both the length and width must be greater than zero (= zero is a trivial rectangle)
6x + 3 > 0
6x > -3
x > -0.5

-2x - 5 > 0
2x + 5 < 0 (multiplying by -1 reverses the inequality)
2x < -5
x < -2.5

This rectangle cannot exist as x cannot be < -2.5 and > -0.5 at the same time!

PolarNik [594]

Step-by-step explanation:

E

working ;

(3x+2)^2

*Apply Perfect Square Formula : (a+b) =a^2+2ab+b^2

a = 3x,b = 2

(3x)^2 + 3x.2+2^2

finally Answer is:

= 9x^2 + 12x +4
