The line of symmetry for a parabola does not always contain which point?

1 answer:

5 0

A parabola's axis of symmetry always goes through the vertex of the parabola. In other words, it is a vertical line that goes through the x-coordinate of the vertex. Therefore, the equation of the axis of symmetry for this parabola is x = 0.

ANSWER

$y = 3x - 3$

EXPLANATION

Let

$y = mx + c$

be the equation.

We can choose any two ordered pairs to determine the equation of the relation.

$(6,15) \: and \: (8,21)$

We find m using the formula;

$m = \frac{y_2-y_1}{x_2-x_1}$

$m = \frac{21 - 15}{8 - 6} = \frac{6}{2} = 3$

The equation becomes

$y = 3x + c$

When x=6, y=15.

This implies that,

$15 = 3(6) + c$

$15= 18 + c$

$15 - 18= c$

$c = -3$

The equation of the relation is therefore,

$y = 3x -3$
