Hello,

Vertex=(-2,-3)

Equation of the parabola is y=k(x+2)²-3
(-5,-2) is a point of the parabola
==>-2=k(-5+2)²-3==>3-2=k*9==>k=1/9

Equation is y=1/9* (x+2)² -3

<span>The coefficient of the squared expression in the parabola's is 1/9</span>

Write the slope and y intercept of each equation:
vichka [17]

Answer:

A) slope = 2, y-intercept = -6

B) slope = -4, y-intercept = 6

Step-by-step explanation:

A) y = 2x - 6

The equation for a line is y = mx + b, where <em>m</em> represents the slope, and <em>b</em> represents the y-intercept. So, to find the slope and y-intercept, all we have to do is look at the line's equation.

Here, the <em>m </em>is 2, so the slope is 2

The <em>b</em> is -6, so the y-intercept is -6

B) y = -4x + 6

Here, the <em>m</em> is -4, so the slope is -4

The <em>b </em>is 6, so the slope is 6

You would graph the equation y = 4x + 6 by plotting a point at the y-intercept of the line, which would be 6. Then, for every time you move one space to the right, you'd plot a point four spaces up to show the slope of four.

Select the similarity transformation(s) that make ABC similar to EDC.
just olya [345]

Given the triangles ABC and EDC

We will find the transformation that makes the triangles are similar

As shown: the triangles are reflected over the y-axis

the rule of the reflection over the y-axis will be as follows:

(x,y)\rightarrow(-x,y)

And as shown, the length of the side AB = 3 units

And the length of the side ED = 1 units

So,

ED=\frac{1}{3}AB

So, the answer will be:

D) (x,y) ⇒ (-x, y)

E) (x,y) ⇒ (1/3 x, 1/3 y)
