Answer:

y= -7x -7

Step-by-step explanation:

All line equations can be represented in the form y = mx + c where a is the gradient or slope and b is the y intercept. (letters used for m and c may vary)

You have been given the slope, = -7 which you can put into y=mx+c

y = -7x + c

The function of a line ^^ means that for any values of x, you multiply it by -7 and add -7. The given coordinates means that when x =0, y = -7. So you can plug these into y = -7x + c , -7 = -7(0) + c . Therefore c = -7

Alternatively, since the value for c is the y intercept, the coordinates immediately give you the answer c. x = 0 which means taht the line intercepts the y axis when y = -7. hence the y intercept = -7

Answer:

$x=3\sqrt{2}$

Step-by-step explanation:

In a right triangle, the "hypotenuse" is the side opposite of the 90 degree angle. That side is "a"

Using pythagorean theorem, we can write:

Leg^2 + Leg^2 = Hypotenuse^2

Note: legs are the other 2 sides, x and x respectively

Now we can write:

$x^2 + x^2 = a^2$

a is 6 meters, so replacing a with 6 and solving we get:

$x^2 + x^2 = a^2\\2x^2=6^2\\2x^2=36\\x^2=18\\x=\sqrt{18}$

To simplify the surd, we can use the property shown below:

$\sqrt{x*y}=\sqrt{x} \sqrt{y}$

Also

$\sqrt{x} \sqrt{x} =x$

Now simplifying:

$x=\sqrt{18} \\x=\sqrt{9*2}\\ x=\sqrt{9} \sqrt{2} \\x=3\sqrt{2}$

Does the parabola open up or down?

bogdanovich [222]

The parabola opens down, the sign of the second difference is positive and the equation of the axis of symmetry is x = 1

<h3>What is a parabola?</h3>

It is defined as the graph of a quadratic function that has something bowl-shaped.

We have given a graph of a parabola.

From the graph:

The parabola opens down.

The sign of the second difference is positive.

The coordinates of the vertex is at (1, 3)

The equation of the axis of symmetry is x = 1

The optimal value of the parabola is at y = 3

The optimal value is considered a max value.

The x-intercepts is at (-1, 0) and (3, 0)

The y-intercept is at (0, 5/2)

Thus, the parabola opens down, the sign of the second difference is positive and the equation of the axis of symmetry is x = 1
