What is the equation of the line that has a slope of 2 and passes through the point (2,9)? A. y - 2 = 2(x + 9)
B. y + 2 = -2(x - 9)
C. y + 9 = -2(x + 2)
D. y - 9 = 2(x - 2)

D

Step-by-step explanation:

use the formula for point slope form, since all of your choices are in that form : y-y1=m(x-x1) (m is the slope)

we're given that m=2 and the point is (2,9)

Substitute into the equation

y-9=2(x-2)

That means that the answer is D

Hope this helps!

4th option is correct xy=-10

if this was to u plzz mark me the brainliest

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 .
