Try this Adjust the sliders on the right. So, now you know how to write an equation in standard form and in point-intercept form. Y went down by 6. Does the position of the y intercept change? There are other ways that linear equations can be written that can help provide useful information for graphing.

Alternately, you would also be correct if you did the rearrangement the other way — that is, subtracted y from both sides, and then subtracted 2 from both sides. Yes, it is rising; therefore, your slope should be positive! Note also that it is useful to pick a point on the axis, because one of the values will be zero.

To write the equation, we need two things: A positive value has the slope going up to the right. Find the equation of this line in point slope form, slope intercept form, standard form. This is our point slope form.

So let's put it in point slope form. And you'll see that when we do the example.

So, for example, and we'll do that in this video, if the point negative 3 comma 6 is on the line, then we'd say y minus 6 is equal to m times x minus negative 3, so it'll end up becoming x plus 3. They really don't have any interpretation directly on the graph.

And then 4 times 3 is When graphing a linear equation, the whole idea is to take pairs of x's and y's and plot them on the graph.

Now adjust the slider for b the interceptletting it settle on, say, Interactive Tutorial Using Java Applet Click on the button above "click here to start" and maximize the window obtained.

Therefore the slope of this line is 2. Play with different values of b and observe the result. However, that assumes that you have the equation written in slope-intercept form, or the actual line itself, from which you can easily pull out values to start with slope-intercept or another similar form.

Any straight line on the coordinate plane can be described by the equation Where: For the new parallel line, we just have to get a new value for D by substituting the external point.

Putting it all together, our point is -1,0 and our slope is 2. It could be a negative 3 and 6.Use our Calculator. You can use the calculator below to find the equation of a line from any two points. Just type numbers into the boxes below and the calculator (which has its own page here) will automatically calculate the equation of line in standard and slope intercept forms.

The standard form for linear equations in two variables is Ax+By=C. For example, 2x+3y=5 is a linear equation in standard form. When an equation is given in this form, it's pretty easy to find both intercepts (x and y).

This form is also very useful when solving systems of two linear equations. & Standard Form & Writing Equations in Slope Intercept Form. Use the graph to determine the.

x - and. y-intercepts. 1) 2) Write an equation, in slope-intercept form, that shows the total cost y (in dollars) of the ticket and x number of bags of skittles. Improve your math knowledge with free questions in "Write equations in standard form" and thousands of other math skills.

For example, 2x – 5y = 10 is in standard form. Students also learn to write the equation of a line in standard form, given the equation of the line in slope-intercept form, the slope and y-intercept of the line, or the graph of the line.

Jun 02, · I know a little about standard form, but I am having a hard time going from slope-intercept form to standard form.

I'm trying to do a line with a slope of -2/3 and a y-intercept of 8/3, so I know the slope-intercept form is y = (-2/3)x + 8/3.
