Triangle ABC has been rotated 90° to create triangle DEF. Write the equation, in slope-intercept form, of the side of triangle ABC that is perpendicular to segment EF. You must show all work to receive credit. Triangles ABC and DEF are shown. A is at 4, 2. B is at 4, 5. C is at 1, 2. D is at 2, negative 4. E is at 5, negative 4. F is at 2, negative 1. Line BC and line EF intersect at point 0, 1.

Answer

4.0/5

Proved: BC and EF have opposite and reciprocal slopes

Step-by-step explanation:

Two lines with slopes that are negative reciprocals of each other are said to perpendicular to each other.

Let m subscript 1 = m1

m subscript 2 = m2

So if m1 is the slope of the 1st (∆ABC)

m2 is the slope of the 2nd (∆DEF)

For both lines to be perpendicular,

m1×m2 = -1
