How do you get the equations for the Euler line?

There are several ways to write an equation for a line. One common form is y = ax + b, where a is the slope and b is the y-intercept (where the line intercepts the y-axis).

It depends on the line. Is it a straight line, a line defined by a polynomial, exponential, logarithmic or other function?

The equation of a line is y=mx+b, when m is the slope of the line and b is the y-intercept.

y = mx + b where:m = slope of the line (rise/run)b = y-intercept (where the line crosses the y-axis)

(I am going to assume you are higher or in grade 9 math) So use the y=mx + bUse the negative reciprocal of the "m"(slope) part. Do this by simply flipping the fraction. This slope will be...
