Evaluate the slope of the line, Mathematics

Evaluate the slope of the line:

Example: What is the slope of the line passing through the points (20, 85) and (30, 125)?

Solution:           

m = 125 -85/30-20 = 40/10 = 4                                   

Given the coordinates of the y-intercept where the line crosses the y-axis [written (0, y)] and the equation of the line, determine the slope of the line.

The standard linear equation form is y = mx + b.  If an equation is given in this standard form, m is the slope and b is the y coordinate for the y-intercept.
