5x = 20 + y Convert to the form y = mx + b y = 5x - 20 In y = mx + b, m is the slope. I'm sure you can figure it out yourself now.
If you mean: 5x-2y = 40 then y = 2.5x-20 whereas -20 is the y intercept and 2.5 is the slope
5x+4y = 20 4y = -5x+20 y = -5/4x+5 Therefore: slope is -5/4 and intercept is 5
The x intercept is the point where y = 0, the y intercept is the point where x =0: For the x intercept: 5x + 2y = 20, but y = 0 => 5x + 0 = 20 => x = 20/5 = 4. So the x intercept is at (4, 0). For the y intercept: 5x + 2y = 20, but x = 0 [The rest of the calculation is left as an exercise for the reader.]
5x = 10 - 20 gives 5x = -10 so that x = -10/5 = -2. Substitute this value in the second equation:-5*-2 + y = 9that is 10 + y = 9so that y = -1
To find the inverse of a function, you have to switch y for x and then solve for y again. These are the steps: y = 5x - 20 x = 5y - 20 5y = x + 20 y = 0.2x + 4 or f(x)^-1 = 0.2x + 4

y = 5x + 1 y - 1 = 5x (y - 1) / 5 = x
Follow this example. f(x) = (x+3)/5 To find its inverse, write y=f(x) y= (x+3)/5 Interchange x and y x = (y+3)/5 solve for y in terms of x 5x=y+3 y=5x-3 The inverse of f(x) is f^-1(x) = 5x-3

Alright this is not very well put, so I have three possible equations that I can think of on the fly. I will attempt to answer all three.1) (4)5x-y=+y +y(4)5x=y/4 /45x=y/4/5 /5[x=(y/4)/5]2) (4x)5x-y=20x2-y=+y +y20x2=y/20 /20[x2=y/20]3) 4x=5x-y+y +y4x+y=5x-4x -4x[y=x]1) (4)5x-y=+y +y[20x=y]2) (4x)5x-y=20x2-y=+y +y[20x2=y]3) 4x=5x-y+y +y4x+y=5x-4x -4x[y=x]
If you mean: 5x-2y = 40 then y = 2.5x-20 whereas -20 is the y intercept and 2.5 is the slope
Write out equation - 10y - 5x= - 20 Negate equation 10y + 5x = 20 Isolate y variable 10y = - 5x + 20 Divide equation by 10 y= -1/2x + 2
write equation in standfrd form y =mx + b where b = y intercept 5x - 2y =20 5x -20 = 2y 5/2 x -10 = y when x = 0 y = -10, the y intercept
y - 9 = -5(x - 4) y - 9 = -5x + 20 y = -5x +20 +9 y = -5x +29
