Find Y
-2x -y = 2
5x+2y=-3
Write an equation in std form
(-3,5) (5,3)
Thanks as always
For some reason I struggle on things that should be easy.
Hi,
multiply the 1rst equation by 2 and then add:
-4x - 2y = 4
5x + 2y = -3
--------------
x = 1 Substitute this value into the 1rst equation:
-2*1 - y = 2
-y = 4
y = -4
I assume that you are looking for the equation of a straight line passing through these two points:
(y - 5)/(x- (-3)) = (3 - 5)/(5 - (-3)) = (-2)/(8) = -1/4 that is the slope of the line:
y - 5 = -1/4*(x+3)
y - 5 = -1/4*x - 3/4
y = -1/4*x + 17/4
