At point-slope form, neither the x nor the y-intercept kind of jump out at you. So if you multiply three and you multiply by seven. Also remember, that when identifying a point from a word problem, "time" is always the x-coordinate.

You could use these two points, you could use the x and y-intercepts as two points and figure out the slope from there. Standard form linear equations Video transcript - [Voiceover] We've already looked at several ways of writing linear equations.

So there you have it, that is our slope intercept form, mx plus b, that's our y-intercept.

Our y went down by 6. Example 1 You are given the point 4,3 and a slope of 2. Now, we can literally just algebraically manipulate this guy right here to put it into our slope intercept form. Slope intercept form is y is equal to mx plus b, where once again m is the slope, b is the y-intercept-- where does the line intersect the y-axis-- what value does y take on when x is 0?

And of course, if you need more help, feel free to ask the volunteers on our math help message board. So once again, we just have to algebraically manipulate it so that the x's and the y's are both on this side of the equation. But point slope form says that, look, if I know a particular point, and if I know the slope of the line, then putting that line in point slope form would be y minus y1 is equal to m times x minus x1.

And this form over here, much easier to figure out the slope and, actually, the y-intercept jumps out at you. And then 4 times 3 is And what I want to do in this video, like we've done in the ones on point-slope and slope-intercept is get an appreciation for what is standard form good at and what is standard form less good at?

This can be written as 3, So one way to do it. If we looked at slope-intercept form, the y-intercept just kinda jumps out at you.

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, our finishing y point is 0, our starting y point is 6. What was our finishing x point, or x-coordinate?

And these are just different ways of writing the same equations. Is your graph rising from left to right?Learn why the Common Core is important for your child. What parents should know; Myths vs. facts. Students will practice working with slope intercept form including writing the equation of line given either A) slope and intercept B) slope and a point or C) two points.

Also students will practice writing the slope intercept equation of a line from its graph. Write the equation in slope-intercept form The first step in finding the slope of a line that is written in standard form is to write the equation in slope-intercept form, y=mx+b. To do this, rearrange the variables.

Recall that the slope (m) is the "steepness" of the line and b is the intercept - the point where the line crosses the y-axis.

In the figure above, adjust both m and b. Write in standard form the equation of the line with slope =-2 and passing through (4,1) Step 1.

The slope-intercept form is given as y=mx+b where m is the slope and b is the y-intercept when x=0 or at point (0,b). Image Source: Google Images. Babies usually follow a straight line of increasing body length as they start growing.

This baby was born 20 inches long (y-intercept), and .
