The point slope formula (if possible) to write an equation of the line given the following information…we
1 answer:
The equation in point slope form is y - 6 = 2(x + 3)
This is from the general point slope template of
The m is the slope, which in this case is m = 2. The is the point the line goes through. In this case,
If you were to solve that equation in bold for y, then you should get y = 2x+12 which is now in y = mx+b form, aka slope intercept form.

Given:
Consider the two points are B(2,3) and B'(-4,-6).
Center of dilation is the origin.
To find:
The scale factors of this dilation that transformed B into B'.
Solution:
If a figure dilatated by scale factor k and center of dilation is the origin, then
It means, the point after dilation is
where, k is the scale factor.
x-coordinate of image is -4 and x-coordinate of original point is 2.
Therefore, the scale factor is -2. It means, the point and image lie on the opposite sides of center of dilation.
