<h3>Answer: -6/5</h3>

Explanation:

The blue diagonal line goes through the two points (0,2) and (5,-4). These are shown as the dark blue enlarged points. You can pick any other points you want that are on the diagonal line, though these are the easiest as they stand out the most.

Use the slope formula to find the slope through these points

m = (y2-y1)/(x2-x1)

m = (-4-2)/(5-0)

m = (-6)/(5)

m = -6/5

The negative slope means the line goes downhill as you move from left to right along the diagonal line.

9x2+4y2 = 36

valentinak56 [21]

Answer:

The foci of the given ellipse = (0 ,-√5 ) and ( 0, √5 )

Step-by-step explanation:

Step(i):-

Given Ellipse 9 x² + 4 y² = 36

$\frac{9x^{2} }{36} + \frac{4y^{2} }{36} =1$

⇒ $\frac{x^{2} }{4} + \frac{y^{2} }{9} = 1$

Step(ii):-

The Major axis lies on y-axis

Foci of the Formula C² = a² -b² = 9-4 =5

C = √5

The Foci is always lie on the major axis(longest) axis, spaced equally each side of the centre

Given ellipse of the foci is lie on Y- axis

Final answer:-

The foci of the given ellipse = (0 ,-√5 ) and ( 0, √5 )
