Answer:
- JK slope: -1/3
- KL slope: 3
- JL slope: -7
- is
- two of the slopes have a product of -1
Step-by-step explanation:
The slope formula is useful.
m = (y2 -y1)/(x2 -x1)
__
JK slope = (1 -2)/(3 -1) = -1/3
KL slope = (-5-1)/(1-3) = -6/-2 = 3
JL slope = (-5-2)/(1-0) = -7
We observe that slopes (-1/3) and (3) have a product of -1, so those line segments are perpendicular. The triangle is a right triangle.
Answer: y = -4/5x - 12
1. First find slope. Since you are trying to find a line perpendicular to y = 5/4x + 10, the slope would be the negative reciprocal of 5/4x.
slope = - 4/5x
2. plug in (-5,-8) and the slope of -4/5 to the point slope form equation
(y-y2) = slope (x-x2)
= y+8=-4/5(x+5)
3. solve and simply y+8=-4/5(x+5)
y = -4/5x - 12 is your answer
In standard form,it should be 0 +0.9 +0.05
