y = x is a straight line through the origin, with a slope of 45 degrees (going from bottom left to top right).y = yx comprises two lines:y = 0 which is the x axis, andx = 1, which is a line parallel to the y axis, and at a distance 1 to its right.
y=f(x) and y =g(x) are two linear equation of x. the intersection of their graphs will tel the solution of the equation f(x)=g(x).

y-3.6=1.6(x-1)
Given two numbers, x and y their difference is |x - y|. |x - y| = x - y if X ≥ y and |x - y| = y - x if x < y
y = x is a straight line through the origin, with a slope of 45 degrees (going from bottom left to top right).y = yx comprises two lines:y = 0 which is the x axis, andx = 1, which is a line parallel to the y axis, and at a distance 1 to its right.
when x is inferior and y is normal then price of increase
y=f(x) and y =g(x) are two linear equation of x. the intersection of their graphs will tel the solution of the equation f(x)=g(x).

Two dimensional graphs have two dimensions: x and y. Three dimensional graphs add a third dimension: z. These give the illusion of depth, while two dimensional graphs do not.
linear (ex. y=x+1) parabolic (ex. y=x**2) hyperbolic
well if you arent doing graphs and you don't know the values for x or y, then you are done
Given two numbers, x and y their difference is |x - y|. |x - y| = x - y if X ≥ y and |x - y| = y - x if x < y
symmetric about the y-axis symmetric about the x-axis symmetric about the line y=x symmetric about the line y+x=0
