Substitute zero for x to find the y-intercept, and substitute zero for y to find the x-intercept.
y = 8
y = -5
Y=5
The idea is to replace "x" by its value, to replace "y" by its value, and then to do the calculations.

y*x8
(y^2)x8
If x = 8 and y = 10 then it is 44.
√(40 x12y9) = 6.3246√(y)* x6 *y4 or 6.3246x6y4.5 ■
If y and x are related inversely, then the equation for y can be said to be:y = k/xTo find the constant k, substitute 12 for y and 6 for x (a pair of values that are known to satisfy the equation).y = k/x12 = k/612 X 6 = k72 = kThe value of the variation constant k is 72.
x0 and y0 usually denote the original condition or value for the variables x and y or may represent the first values in an array of values. Some final condition my be represented by x1 or y1 or x12 or y12 depending on how many conditions you want the values of x and y for.
if y=1/4x and x=,find y
y
if y = 5x – 8 find the value of x if y = 7
The problem is If y³−3y+4x=0, find y′ by implicit differentiation
