Answer:

(3, -4)

Step-by-step explanation:

The correct equation is:

y=\sqrt{x-2}-5

From the list of given points, we have to identify which point lies on the graph. This can be done by using the value of x-coordinates from the given points and see if they result in the corresponding y-coordinate:

For point (1, 4)

y=\sqrt{1-2}-5=\sqrt{-1}-5, This is not equal to 4, so it does not lie on the graph of given function.

For point (3, -4)

y=\sqrt{3-2}-5=\sqrt{1}-5=-4, The answer ans corresponding y-coordinate are the same. This means, (3, -4) point lies on the graph of given function.

Likewise, checking for 3rd and 4th point we find out that they do not lie on the graph.

So the correct answer is (3, -4)

I need help and it is y intercept and x intercept
Neporo4naja [7]

Answer:

y-intercept (0, -3) and x-intercept (3/2, 0)

Step-by-step explanation:

y + 5 =2(x + 1)

y + 5 =2x + 2

subtract 5 from both side

y =2x -3

-3 is the y-intercept because in y=mx+b, b is the y-intercept and it always starts at 0.

To find the x-intercept, we need to plug in 0 for y in y =2x -3

0=2x -3

add 3 to both sides

2x=3

divide both sides by 2

x=3/2 and so the x-intercept is 3/2 and it always starts at 0.

What is the equation of the line that has a slope of 1 and passes through the point (8,6)?
Airida [17]

Answer:

The equation of this line in point-slope form would be y - 6 = (x - 8)

Step-by-step explanation:

In order to find this, we simply plug into the point-slope form using the known information.

y - y1 = m(x - x1)

y - 6 = 1(x - 8)

y - 6 = x - 8

Which rule describes the transformation that is a reflection across the x-acis
Alla [95]

Answer:

When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the line y = -x, the x-coordinate and y-coordinate change places and are negated (the signs are changed). the line y = x is the point (y, x). the line y = -x is the point (-y, -x).
