Choose the term that best fills in the blank to complete the statement. A dilation is a transformation that maps every point on a line segment to a point on a parallel line segment. The image has a length that is determined by the preimage and a scale factor, which is a fixed _[blank]_ of the original segment's length.
A. width
B. length
C. multiple
D. distance

go on the tube you might find some information there

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
