ILL MARK BRAINIEST IF YOU CAN DO THIS RIGHT!!!
Bumek [7]

Answer:  Slope: -1/2  

Step-by-step explanation:  To find slope take 2 points that lie on the line and use this formula to solve:  <em> </em>I will use (0, -2) and (2, -3) to solve

                                                                       ↑    ↑           ↑   ↑

y2 - y1                                                             x1  y1          x2  y2

-----------

x2 - x1

So, for this question, substitute the x and y values from the points above to solve.

-3 - (-2)      

----------- =  - 1/2

2 - 0

Hope this helped. :)

son4ous [18]
Alvin's age + Elga's age = 84
2R + R                             = 84 
3 R                                   = 84
3/ 3 R = 84/ 3 
R = 28 
Elga's age is 28

Which special version of the Pythagorean Theorem can you use to find the length of any square's diagonal, d, using only the leng
kodGreya [7K]
The square's diagonal is the triangle's hypotenuse.

the original Pythagorean theorem is  a^{2} +  b^{2} = c^{2}   where a and b are the two sides and c is the hypotenuse.

that means the Pythagorean theorem for this question is:

s^{2} + s^{2} = d^{2}  or 2( s^{2} )= d^{2}
