Points X(4, 1), Y(7, 1) and Z(4, 6) are in standard (x,y) coordinate plane. If XYZW is a rectangle, what is the length, in coordinate units, of XW

y = - x -

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - , then

y = - x + c ← is the partial equation

To find c substitute (2, - 4 ) into the partial equation

- 4 = - + c ⇒ c = - + = -

y = - x - ← equation of line
