What is the order of rotational symmetry for a rhombus

answer:

order two

Step-by-step explanation:

When we look at the above images of rhombus, it fits on to itself 2 time during a full rotation of 360 degrees.  

Hence, a rhombus has rotational symmetry of order 2.

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)
