Answer:

B''C''=3BC

Step-by-step explanation:

we know that

The length of segment B''C'' is equal to the length of segment BC multiplied by the scale factor

step 1

Find the length of segment BC

the formula to calculate the distance between two points is equal to

d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}

we have the points

B(1,-3),C(-3,-3)

substitute the values

BC=\sqrt{(-3+3)^{2}+(-3-1)^{2}}

BC=\sqrt{(0)^{2}+(-4)^{2}}

BC=4\ units

The segment B''C'' is equal to the segment BC multiplied by the scale factor

The scale factor is 3

so

B''C''=BC(3)

B''C''=3BC

substitute

B''C''=3(4)=12\ units
