Polygon ABCDEF is translated 12 units to the left to create polygon
A′B′C′D′E′F′. If DE = 7 units, what is D′E′ ?

Which of the following is the shape of a cross section of the figure shown below

Which statements are true? check all that apply. the line x = 0 is perpendicular to the line y = –3. all lines that are parallel to the y-axis are vertical lines. all lines that are perpendicular to the x-axis have a slope of 0. the equation of the line parallel to the x-axis that passes through the point (2, –6) is x = 2. the equation of the line perpendicular to the y-axis that passes through the point (–5, 1) is y = 1.

What does the sign of the slope tell you about a line?
