Determine the equation of line EF perpendicular to BC at intersect 0,1
<em>The question has missing attachment but it can still be solved;</em>
First, we need to determine the slope of BC using

Where
<em></em>
<em> Point B</em>
<em></em>
<em> Point C</em>
Substitute these values in the above formula



Next is to determine the slope of EF;
Since, there are perpendicular: we have

Substitute -1 for m1


Next, is to determine the slope of EF at intersect (0,1).
The formula to use is:

In this case;

Substitute values for m2, x1 and y1


Open the bracket

Add 1 to both sides


Hence;
The equation is 
The answer is half. Since it divides two then it is half of the original. Please give me brainiest

Answer:
y = x² + 11x + 24
Step-by-step explanation:
y = (x + 3)(x + 8)
Expand
y = x² + 8x + 3x + 24
Combine like terms
y = x² + 11x + 24
That sounds like it would be a reflection, like rut would be reflected over the line
