Slope - Intercept
What is slope-intercept?
Slope-intercept is the most common way of writing the equation of a straight line (a linear function).
Linear functions look like this:

The format for a slope-intercept equation is y = mx + b.
Where:
Basically, to find the equation when the slope and y-intercept are given, just plug in these values into y = mx + b:
Slope = 5 and y-intercept = 5:

Therefore, the equation is y = 3x + 5.
