A Line Segment has the points (1,-2), and (3,-2). What are the new points after its dilated by a scale factor of 3/2 or 1.5
jeka57 [31]

Answer:

The new points after dilation are

(3/2, -3) and (9/2,-3)

Step-by-step explanation:

Here in this question, we want to give the new points of the line segment after it is dilated by a particular scale factor.

What is needed to be done here is to multiply the coordinates of the given line segment by the given scale factor.

Let’s call the positions on the line segment A and B.

Thus we have;

A = (1,-2) and B = (3,-2)

So by dilation, we multiply each of the specific data points by the scale factor and so we have;

A’ = (3/2, -3) and B’= (9/2,-3)

Given statement: "a number <em>a</em> is always less than another number <em>b."</em>

<em />

We use "<" or ">" sign to show less than or more than comparison in a mathematical statement.

If <em>a</em> is less than <em>b </em>then it can represented as

<em>a < b</em>

The expressions expresses the relationship between <em>a</em> and <em>b</em> would be:

<em>a < b</em>
