First, you have to get y by itself by dividing each side by 4:
4y=4x-8
y=x-2
Then, the x-coordinate must equal zero if it is a y-intercept, so substitute 0 for x:
y=0-2
y=-2
The y-intercept would be (0, -2 )

How do you write 8x plus 4y equals 20 in fuction form?
8x+4y=20 4y=-8x+20 y=-2x+5 f(x)=-2x+5
What is the slope x 4y equals 12?
I presume that since you labeled this as a Calculus problem that you mean x * 4y = 12? x * 4y = 12 ---> 4y = 12 / x ---> y = 3 / x ---> y = 3 * x^(-1) You will notice that this function is not a line, but a curve. The slope will be different at different points on the line. Thus, we can't find the slope of the entire function, but we CAN find a function which gives us the slope of a tangent line at any point on the function. We do this by taking the derivative. For f(x) = a * x^(n) f'(x) = a * n * x^(n-1) Using a = 3 and n = -1, we have: y = f(x) = 3 * x^(-1) dy/dx = f'(x) = 3 * -1 * x^(-1 - 1) = -3 * x^(-2) So your answer will be: dy/dx = -3 * x^(-2)
