Find the starting point
xy
if:
a. the point
is the image of a pure dilation with a factor of 2.
b. the point
is the image of a pure dilation with a factor of
1
2
.
c. the point −10
35
is the image of a pure dilation with a factor of 5.
d. the point
4
9
16
21
is the image of a pure dilation with a factor of
2
3
.

b

step-by-step explanation:

multiply terms on numerator/ denominator by (x - 1)

= ← distribute numerator/ denominator

= ← simplify

=

= → b

d

step-by-step explanation:

the two points from this line are   (0,4)   & (2,-2)

we can call

now, lets find the slope (m):

now finding b (the y intercept). this is the point at the y-axis where the line cuts the axis. looking at the graph, it is y = 4. so the point is 4. hence b = 4

the slope-intercept form is given by  

putting the points, we have:

d is the correct answer.

if i knew id you bro,, my bad
