So let me see if I can remember that and type that in. Discussion The standard form of a line is just another way of writing the equation of a line.
Instead of my forcing another worksheet down your throat, go back and look at some of the examples on the previous worksheets and see if you can find the slope. So let's do this, let's figure out all of these forms.
Let's quickly revisit standard form. Now let's see, am I done? If there was a common factor for all three of these numbers then I would divide all of them the way I did in that previous example. Now, we must convert to standard form.
And when someone puts this little subscript here, so if they just write an x, that means we're talking about a variable that can take on any value. So the way that it's written right now, this is slope intercept form.
This is probably the easiest concept to get across, once your students have become comfortable with converting linear equations into standard form. So let's do slope intercept in orange.
I'm just saying, if we go from that point to that point, our y went down by 6, right? However, you must be able to rewrite equations in both forms.
And then we want our finishing x value-- that is that 6 right there, or that 6 right there-- and we want to subtract from that our starting x value.
Well, our starting x value is that right over there, that's that negative 3. But, through this process of writing and reflecting, I have learned from my experience. Yes, it is rising; therefore, your slope should be positive! You get 2x, divide this by two you'll get plus y is equal to 5.
So this, by itself, we are in standard form, this is the standard form of the equation.Slope-intercept form has y = mx + b To convert slope-intercept form to standard form, subtract mx from both sides of the equation.
-mx + y = b If m is a fraction, multiply the equation by its denominator. Writing Linear Equations in Slope-Intercept Form Algebra 1 Exploration The graph at the right shows the cost of a smart phone plan. 1. What is the y intercept of the line? Interpret the y- intercept in the context of the problem.
2. Approximate the slope of the line. Interpret the slope. 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.
Writing Algebra Equations Finding the Equation of a Line Given Two Points. We have written the equation of a line in slope intercept form and standard form.
We have also written the equation of a line when given slope and a point. Now we are going to take it one step further and write the equation of a line when we are only given two points that are on that line.
Write the point-slope form, slope-intercept form, and standard form of an equation for a line that passes through (-1,2) with slope 4. This question is for my assignment and I need some help understanding the question.
I am a little rusty when it comes to slope related topics.
