Why is it important to use a straightedge when copying a line segment?(1 point) Since line segments can be any length, it is important to use a straightedge for longer line segments. A straightedge is less important when drawing short line segments though. Since lines must be straight, and line segments are sections of lines, a straightedge must be used to keep the line segment straight. Since rulers are straightedges, it is important to use them to make sure the length of line segments are the same. Using a straightedge helps you to draw the new line segment at the same angle as the original line segment.

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is

3

step-by-step explanation:

divide 13.5 by 9 to get the scale factor. it equals 1.5

2 * 1.5 = 3
