How do you write the equation for a line that passes through points (2,1) and (0,7)?
To find the equation of a line passing through two points you must first find the slope of the line.
The slope can be found by using the formula:
Next we can use the point-slope formula to find the equation for the line passing through these two points.
The point-slope formula states:
We can substitute
Solving for the slope intercept form gives:
