Want some practice finding the y-intercept of a line?In this tutorial, you're given the slope of a line and a point on that line and asked to find the y-intercept.
Watch this tutorial and see what needs to be done to write an equation in slope-intercept form!
In this tutorial, you'll see how write an equation in slope-intercept form that represents the information given in the word problem. Looking for some practice converting the equation of a line into different forms? Follow along as this tutorial shows you how to take a linear equation from slope-intercept form and convert it into standard form and point-slope form.
– then you're dealing with a straight-line equation.
There are different types of "standard" formats for straight lines; the particular "standard" format your book refers to may differ from that used in some other books.
(There is, ironically, no standard definition of "standard form".) The various "standard" forms are often holdovers from a few centuries ago, when mathematicians couldn't handle very complicated equations, so they tended to obsess about the simple cases.
Nowadays, you likely needn't worry too much about the "standard" forms; this lesson will only cover the more-helpful forms.
We have two special calculators dedicated to such an equation, namely the parabola calculator and the quadratic formula calculator.
There you can find a full description of these types of functions!
This is the equation of the line in slope-intercept form.
Borrowing from the two previous steps, the example line would be y = 1x 4, which simplifies to y = x 4.
