Answer:

The equation of line is 2x-3y=15.

Step-by-step explanation:

Given;

Slope is 2/3 and crosses y axis at (0,-5).

Now, the point = (0,-5) that is $(x_{1},y_{1})$ and the slope of the line = 2/3 which is $m$ .

So, now putting the formula for the equation of the line:

$y-y_{1} =m(x-x_{1})$

$y-(-5)=\frac{2}{3}(x-0)$

$y+5=\frac{2}{3}(x-0)$

On solving equation we get :

$3y+15=2x-0$

$15=2x-3y$

$2x-3y=15$

Therefore, the equation of line is 2x-3y=15.

What are the coordinates of the endpoints of the midsegment for DEF that is parallel to DE

Nutka1998 [239]

Answer:

$\left(\dfrac{x_D+x_F}{2},\dfrac{y_D+y_F}{2}\right),$ $\left(\dfrac{x_E+x_F}{2},\dfrac{y_E+y_F}{2}\right).$

Step-by-step explanation:

Let points D, E and F have coordinates $(x_D,y_D),\ (x_E,y_E)$ and $(x_F,y_F).$

1. Midpoint M of segment DF has coordinates

$\left(\dfrac{x_D+x_F}{2},\dfrac{y_D+y_F}{2}\right).$

2. Midpoint N of segment EF has coordinates

$\left(\dfrac{x_E+x_F}{2},\dfrac{y_E+y_F}{2}\right).$

3. By the triangle midline theorem, midline MN is parallel to the side DE of the triangle DEF, then points M and N are endpoints of the midsegment for DEF that is parallel to DE.
