f(x)= (4 - 5y)/8
f(y)= (4 - 8x)/5

8+y = 7+5y y-5y = 7-8 -4y = -1 y = 1/4
If the equation is -20x-5y=40 then the answer is -5y=20x+40 which equals y=-4x-8 If the equation is -20x+5y=40 then the answer is 5y=20x+40 which equals y=4x+8
5x + 5y = 19x = 3.8 - yory = 3.8 - x
standard form
$48x + 5y" is an expression. It is not a function and so cannot be written as a function.
The standard form, which is the form that can be generalised to 3 or more dimensional spaces, is 4x + 5y - 13 = 0
(9,3)
Yes, 3x = 5y is a linear function.
(-5, 2)
The Commutative Property of Addition.
y = (11-4x)/5
x=(-5y-1)/3
If: 3x-5y+10 = 0 Then: -5y = -3x-10 And: y = 0.6x+2 in slope-intercept form
5y + 7 = 25y = -5y = -1
