Which statement completes step 6 of the proof? the product of the slopes of and is −1; therefore, lines f and g are perpendicular. that's the answer
step 1
is parallel to the y-axis, and is parallel to the x-axis.
step 2
δjkl was rotated 90° clockwise to create δj'kl'. point k did not change position, so it remains point k. therefore, δjkl ≅ δj'kl'.
step 3
is perpendicular to the y-axis, and is perpendicular to the x-axis.
step 4
lies on line f and has a slope of 3.
step 5
lies on line g and has a slope of .
step 6
?
a: the product of the slopes of and is −1; therefore, lines f and g are perpendicular.
b: the slopes of and are congruent; therefore, lines f and g are parallel.
c: the product of the slopes of and is −1; therefore, lines f and g are perpendicular.
d: the slopes of and are congruent; therefore, lines f and g are parallel.
