Answer:

7/3

Step-by-step explanation:

The distances have the ratio ...

(Q -P) = (2/3)(R -P)

Q = P +(2/3)R -(2/3)P = (2R +P)/3

Qy = (2Ry +Py)/3 = (2·0 +7)/3 = 7/3

Answer:

point slope form: y-3= $-\frac{3}5}$ (x+2)

slope-intercept form: y= $-\frac{3}{5}$ x+ $\frac{9}{5}$

Step-by-step explanation:

so to find point-slope form, you first have to find the slope of the line

--slope = $\frac{y_{2}-y_{1} }{x_{2} -x_{1} }$ = $\frac{0-3}{3+2} =-\frac{3}{5}$ (you have to use the two points shown: (-2,3) and (3,0) to plug in for y1, y2, x1, and x2 to find the slope.)

so your slope is $-\frac{3}{5}$ .

Now all you have to do is use one of the points (-2,3) to sub in for y1 and x1 in the point-slope form equation.

Therefore, you get y-3= $-\frac{3}{5}$ (x+2) for point-slope form.

Now for slope-intercept form, you already have the slope because you found it to complete the equation for point slope form

slope = $-\frac{3}{5}$

Now slope intercept form is y=mx+b, where m is the slope and b is the y-intercept.

So, far we have y= $-\frac{3}{5}$ x+b

the easiet point to use for the x and y values is (3,0)

so, lets substitute: 0= $-\frac{3}{5}$ (3)+b, which becomes 0= $-\frac{9}{5}$ +b

add $-\frac{9}{5}$ to both sides to get b= $\frac{9}{5}$

Now you have both the slope and the y-intercept so you can now write the line in slope-intercept form.

You get $y=-\frac{3}{5}x +\frac{9}{5}$ .

Center: (10,-10)

This is the standard form equation $\frac{(x - 10)^2}{100} + \frac{(y + 10)^2}{-100} = 1$

What is the ellipse?

The equation for an ellipse is typically written as x² a² + y² b² = 1. x² a² + y² b² = 1. An ellipse with its origin at the center is defined by this equation. The ellipse is stretched further in both the horizontal and vertical directions if a > b, a > b, and if b > a, b > a, respectively.

The standard form of the equation of an ellipse with center (h, k)and major axis parallel to the x-axis is:

$\frac{(x - h)^2}{a^2} + \frac{(y - k)^2}{b^2} = 1$

where,

a > b

the length of the major axis is 2a

the coordinates of the vertices are (h±a,k)

the length of the minor axis is 2b

the coordinates of the co-vertices are (h,k±b)

the coordinates of the foci are (h±c,k),

where c² = a² − b².

so,

$\frac{(x - 10)^2}{100} + \frac{(y + 10)^2}{-100} = 1$

Hence, this is the standard form equation $\frac{(x - 10)^2}{100} + \frac{(y + 10)^2}{-100} = 1$ .
