Where m is the slope of the line and b is the y-intercept. You can use this equation to write an equation if you know the slope and the y-intercept.
In many cases the value of b is not as easily read. In those cases, or if you're uncertain whether the line actually crosses the y-axis in this particular point you can calculate b by solving the equation for b and then substituting x and y with one of your two points.
We can use the example above to illustrate this. We've got the two points -3, 3 and 3, From these two points we calculated the slope. To summarize how to write a linear equation using the slope-interception form you Identify the slope, m. This can be done by calculating the slope between two known points of the line using the slope formula. Find the y-intercept.
This can be done by substituting the slope and the coordinates of a point x, y on the line in the slope-intercept formula and then solve for b. Once you've got both m and b you can just put them in the equation at their respective position.

I'm not good at algebra, but I might be able to help. Good Luck! Everyone gets a different test, with similar answers, so although the questions can be reversed, or are the same, our answers are still not in the correct order!
So don't trust every single answer you see here! You really think it'd be the same test? And you say you're 8th graders? Here are the genuine answers. B This is for grade 9 Connexus. I don't know what answers you all got but I need help, and all you guys have said different answers which one should I go with?
All you guys are idiots The answers are different for every test. I know this are fake because, there really is 24 but the last 2 supposed to be hand written so some of you are just putting random answer on how many questions you see.
Guys, all tests have different answers so I thing yall should man up and do it yourself! Do you know why? BTW, that affected my grade alot in a good way. Be careful. Thanks "I'm Smart" now you just made my self-esteem lower down and want to jump off. First Name. Which graph represents the solution of the given system? The first question is Which graph represents the.
I really need help with the Equations and Inequalities Unit Test p1 and 2!! I am trying to decide on what books I should use to prepare for this examine.
The following is what is going to be covered in this examine:. How many solution sets do systems of linear inequalities have?
Do solutions to systems of linear inequalities need to satisfy both inequalities? If so what are some examples? In what case might they not? I am taking the Equations and Inequalities Unit Test, and I'm having a lot oof truble, I am dyslexic and I'm aalready failing math, if someone could please explain the first question to me I'm sure I wil figure the rest.
