Writing a Linear Equation

Slope intercept form:

Slope:

How to solve for…

y-intercept:

1) From a graph: Look at where the line crosses the y-axis

OR

2) Plug in a point (x,y) the graph goes through into the equation y=mx+b and solve for b

Or…

Example 1:

Example 2:

A line passes through the points (-1,1) and (2,10)

m = rise
