Rearranging to slope-intercept form and finding domain and range

<p>- Hi. We'll work on this question right here. So this one right here, we need to figure out the slope, the y-intercept, the domain and range. So let's do the slope and the y-intercept first. So what we have here is a y equal to three over two x plus one. Now if you remember, this is the same thing as the y equals to the slope and the y-intercept form. So this is an m x plus the b, right? So it's gonna say right there. The three over two is your slope automatically. So you know the slope is just going to be three over two. The y-intercept is just gonna be the b, so remember the b in the equation, this one right here is actually your y-intercept, So in this case, it's gonna happen at the y equals to one, all right? Now if you want to figure out the domain and range, you know, this is a linear function. Actually for all linear functions, they either go like this or this way or they go flat or they kinda go up and down sometimes. So as long as you're not doing these two, you're doing one of these guys here, the domain and range is actually all real in every single case, So if you actually draw this on the graph to prove it to yourself, you will actually have a y-intercept at the point one, so a y equals to one, sorry. That's a one right there. And the slope would be up three over two, so pretend I go up three and over two, then that's my next point. Then you'll be drawing like a straight line across with the arrows on both ends. Now, seeing the graph like this, it's really straight forward that the domain and the range, it's just going to be all real for both cases. So this is just the way that I write down all real numbers. So my x is all real numbers and my the range is just the y is for all real numbers, So that's your final answer right here. Thanks for watching.</p>

Comparing slope-intercept, general, and point-slope forms

The slope intercept form is used to find the <a href="[[glossary.html|{"keyword":"y-intercept"}]]">y-intercept</a> and the slope of a straight line. If you look closely, it is a linear function too; meaning the function can tell you its domain and range.
