What is the equation of the two points 3,5 and 5,0

DiKsa [7]

Answer:

The equation of the line is y = -5/2x + 25/2

Step-by-step explanation:

To find the equation of the line, we first need the slope. We can get that by using the slope formula.

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

m = (5 - 0)/(3 - 5)

m = (5)/(-2)

m = 5/-2

m = -5/2

Now that we have the slope, we use the slope and the given point in point-slope form. Then we solve for y.

y - y1 = m(x - x1)

y - 0 = -5/2(x - 5)

y = -5/2x + 25/2

HELP!!!!

OverLord2011 [107]

Answer:

Step-by-step explanation:

You just need the distance formula here. It's very simple to follow:

$d=\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }$

which, for us, looks like this:

$d=\sqrt{(13-4)^2+(19-7)^2}$ and

$d=\sqrt{9^2+12^2}$ and

$d=\sqrt{81+144}$ and

$d=\sqrt{225}$ so

d = 15

Perform the addition. (3x² + 3x - 5) + (-7x² + 9)

lakkis [162]

The question is asking us to find the sum. To do this, let's first write the original equation and then take it from there.
$(3 x^{2} + 3x - 5) + (-7 x^{2} + 9)$ 
Use distributive property:
 $3 x^{2} + 3x - 5 - 7 x^{2} + 9$
Combine Like Terms:
$
-4 x^{2} +3x+4$
Therefore, the answer to your question is -4x² + 3x + 4. Hope this helps and have a fantastic day!
