Awalking path across a park is represented by the equation y = –2x + 5. a new path will be built perpendicular to this path. the paths will intersect at the point (–2, 9). identify the equation that represents the new path.

A line perpendicular to y = -2x + 5 will have an equation in the form of:

y = (1/2)x + b

Since the graph must intersect (-2,9), we plug in this point to solve for b.

9 = (1/2)*(-2) + b

9 = -1 + b

10 = b

So the equation is:

y = (1/2)x + 10

The answer is A.

by definition, an arc subtended by a central angle of some given measure has the same measure. so .
