Answer:

slope: -1/2

Y-intercept: -1

Step-by-step explanation:

Get Y by itself by subtracting x on both sides

2y= -x -2

Now divide both sides by 2 to cancel the two connected to the y:

Y = -1/2x -2/2

So y= -1/2x -1

Y=mx+b so m is the slope and b represents the y-intercept

Answer:

$120

Explanation:

Data provided as per the given question below:-

Investment = $4,000

Coupon rate in percentage = 3%

The computation of yearly return is shown below:-

Yearly return = Investment × Coupon rate in percentage

= $4,000 × 3%

= $120

Therefore for computing the yearly return we simply investment with coupon rate in percentage.

Parallelogram JKLM has vertices J(-1, 6), K(0, 9), L(6, −3), and M(3, −3). What is the coordinates of the image if the parallelo

Digiron [165]

Answer: $(\dfrac13,-2),\ (0,-3),\ (-2,1),\ (-1,1) .$

Step-by-step explanation:

Transformation rule for dilation:

$(x,y)\to(kx,ky)$ , where k = scale factor

Given : Scale factor = $-\dfrac13$

Parallelogram JKLM has vertices J(-1, 6), K(0, 9), L(6, −3), and M(3, −3)

Vertices after dilation:

$(-1,6)\to(-1\times\dfrac{-1}{3},6\times\dfrac{-1}{3})=(\dfrac13,-2)$

$(0,9)\times(0\times-\dfrac13,9\times-\dfrac13)=(0,-3)$

$(6,-3)\to(6\times-\dfrac13,\ -3\times-\dfrac13)=(-2,1)$

$(3,-3)\to (3\times-\dfrac13,\ -3\times-\dfrac13)=(-1,1)$

Hence, the coordinates of the image if the parallelogram = $(\dfrac13,-2),\ (0,-3),\ (-2,1),\ (-1,1) .$
