y=mx+b What is each letter's meaning in the equation?

Question

y=mx+b

I just need a definition on m,x, y, and b.

Thanks!

Answer 1

y = the dependent variable, which is on the vertical axis (the ordinate)

m = slope of the line described by the equation

x = independent variable, which is on the horizontal axis (the abscissa)

b = y-coordinate of the y-intercept, which is the point where the line crosses the y-axis
