Answer:
Line 1: -2
Line 2: 2
Line 3: 2
Line 1 & 2 is parallel.
Line 2 & 3 is neither.
Step-by-step explanation:
To find the slope of a line use the slope formula and substitute the points into it:
Line 1
Line 2
Line 3
Parallel lines have the same slope and perpendicular lines have negative reciprocal slopes.
Line 1 & 2 is parallel.
Line 2 & 3 is neither.
Answer:
7
Step-by-step explanation:
<span>Find the focus and directrix of the parabola with the given equation. Then graph the parabola.
y^=-12x
**
y^2=-12x
This is an equation of a parabola with a horizontal axis of symmetry.
Its standard form: (y-k)^2=4p(x-h), with (h,k) being the (x,y) coordinates of the vertex.
For given equation:
Vertex(0,0)
4p=12
p=3
Focus:(-3,0)
Directrix: x=3
see the graph below as a visual check on the answers:
..
y=±(-12x)^.5</span>
The answer would be 48 degrees
