Simultaneous equations.
No.
5x + 5y = 19x = 3.8 - yory = 3.8 - x
(6, -4)
you cant
slope = -1
No. No. No. No.
If: 3x-5y = 25 Then: -5y = -3x+25 And: y = 3/5x-5 So: slope is 3/5 or 0.6 and the y intercept is -5
x = 6, y = -4
-5x=3+y x=-1/5y-3/5
2X + 5Y = 6 5Y = - 2X + 6 Y = - 2/5X + 6/5 ----------------------------------and 5X - 2Y = 8 2Y = - 5X + 8 Y = - 5/2 + 4 ------------------- Look like intersecting lines, though not perpendicular
This is a system of equations:-x + 5y = 10-5x + 2y = 27Multiply the first equation by 5.-5x + 25y = 50Subtract the 2 equations:23y = 23Solve:y = 1-x + 5(1) = 10-x = 5x = -5Thus, the ordered pair is (-5, 1).
