How can you find the slope of a line from the coordinates of two points on the line?

use the slope formula to find the slope of a line given the coordinates of two points on the line and the slope formula is m=( y2- y1)/ (x2 - x1) or the change in the y values over the change in x values.The coordinates of the point represent x1 and y1. The coordinates of the second points are x2, y2.

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 .
