This shows the method of using the point-slope form to write the equation, then solving that form for y to get y = mx + b.
|
|
The informaton given here can be entered directly into the y = mx + b or slope-intercept form. Then the y-intercept is used as a starting point where you apply rise over run to the given slope to…

Two quick demonstratoins of a rational expression containing radicals being ratioinalized by multiplication of a form of one to transform a radical in the denominantor to a whole number.
|
|
This discusses what rationals and irratioinals are, then goes on to demonstrate how to eliminate any radical number in the denominator.
|
