Given:
The three points are W(0,-2), I(2,0) and L(5,k).
To find:
The value of k for which the given points are collinear.
Solution:
We know that, three points are collinear if the area of the triangle formed by these three points is 0.
The three points are W(0,-2), I(2,0) and L(5,k). So,
Adding 6 on both sides, we get
Therefore, the correct option is E.
Answer:
Step-by-step explanation:
<u>Factored form of a parabola</u>
where:
- p and q are the x-intercepts.
- a is some constant.
Given x-intercepts:
- (1+√5, 0)
- (1-√5, 0)
Therefore:
To find a, substitute the given point (4, 8) into the equation and solve for a:
Therefore, the equation of the parabola in factored form is:
Expand so that the equation is in standard form:
