I need three points on a graph but I need help
mezya [45]
-3y = 2x - 7

when x = 0
-3y = -7
 y = 7/3
 y = 2 1/3(2 and 1/3)

when y = 0
2x - 7 = 0
2x = 7
  x = 3.5

when x = 2
-3y = 2(2) - 7 
-3y = -3
   y = 1

when x = -1 
-3y = 2(-1) - 7 
-3y = -9
   y = 3

Answer ( you can 3 of those below for your ordered pairs)

 ordered pairs
  (0, 7/3), (3.5, 0) (2, 1), (-1, 3)

Find the length of the third side. If necessary, round to the nearest tenth.914
Zina [86]

The given trinagle is a right angle triangle. let the missing side be x. To find x, we would apply the pythagorean theorem which is expressed as

hypotenuse^2 = one leg^2 + other leg^2

From the triangle,

hypotenuse = 14

one leg = 9

other leg = x

Thus, we have

\begin{gathered} 14^2=9^2+x^2 \\ 196=81+x^2 \\ x^2\text{ = 196 - 81 = 115} \\ x\text{ = }\sqrt[]{115} \\ x\text{ = 10.72} \end{gathered}

To the nearest tenth, the length of the third side is 10.7
