Answer:
a. segment DE and segment EF are congruent to each other but not to segment DF, and their slopes are not related.
Step-by-step explanation:
In order for a triangle to be isosceles, two of the line segments must be congruent. (eliminates choices C and D)
If the slopes of the congruent segments are negative reciprocals of each other, the triangle is a right triangle, not an acute triangle. (eliminates choice B)
With choices B, C, D eliminated, we are left with choice A.

However, <em>that necessary description is not sufficient</em> to constrain the triangle to be an acute triangle. In order for the triangle to be acute, the third side must be less than √2 times the length of either of the congruent sides.
The correct answer is "none of the above."
can u take a better pic :) so its more clear!!
Step-by-step explanation:
C because it has the x variables in the numerator. This is wrong because the x axis represents horizontal movement and slope is rise over run, not run over rise
I believe the answer to that question is -20
x + 17 ≥ -3
Isolate the x. Subtract 17 from both sides
x + 17 (-17) ≥ - 3 (-17)
x ≥ -3 - 17
x ≥ -20

x ≥ -20 is your answer

hope this helps
