Answer:
The parent function is
That Parabola's equation is
Step-by-step explanation:
I can't really explain much, but the top equation is a formula for <em>all </em>equations for a parabola. h and k are the x and y-values of the vertex. a is, well, a.
How did I find the equation of the parabola? Simple. Since the vertex is on the origin, h and k are 0. Also, because it intercepts (2,4) and (1,1), a=1.
Answer:
B) y = x + 2
Step-by-step explanation:
Coordinates of point C =
Coordinates of point D=
To find the equation of segment CD
Formula :
Substitute the values in the formula :
y-12=x-6
y=x+6
When two lines are perpendicular to each other the product of their slopes is -1
Let the slope of perpendicular line be x
So, -1 \times x = -1
So, x =1
General equation : y = mx+c
So, Option B has slope = 1
So,the equation of the line that's a perpendicular bisector of the segment connecting C (6, –12) and D (10, –8) is y = x + 2
