Required

Select all equations that could be used.

Equation that could be used in place of must have the same slope.

Calculating the slope of

Make y the subject

Using y = mx + b

Where

The slope is -4

Option A.

Open bracket

Collect Like Terms

Make y the subject

The slope of this line is 4;

Hence, it can not be used.

Option  B.

The slope of this line is -4;

Hence, it can be used.

Option  C.

Solve for4y

Solve for y

The slope of this line is -4;

Hence, it can be used.

D.

The slope of this line is -4;

Hence, it can be used.

E.

Solve for 2y

Solve for y

The slope of this line is -2;

Hence, it can not be used.

From the calculations above, equations B, C and D are equivalent

step-by-step explanation:

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
