# Using Slope and y intercept

Use the formula

to find the slope of each line. Use the vertical intercept to complete the equation in the form

Worked Example: example slope y intercept

# Using Two Points

Use the formula

to find the slope of each line.

Now substitute the and coordinates of one of the points to find the value . Type in your formula in the form

Example: Example two points

# Using One Point and the Slope

The formula

Printed practice:Grade 10 Point Slope

is very useful for the next applet. But no need to be bound by one method, try out your own.

Example: Example slope point
