Slope intercept form, standard form, and point-slope form
I'll tell you what I know while I work on your teeth.
That would be great!
Slope intercept form is the easiest in my opinion. Instead of solving to find the points, they are given to you in the formula. You can instantaneously pull the slope and the y-intercept. The formula is y=mx+b. "M" is the slope and "B" is the number on the y-axis the point goes on.
Okay! What about standard form?
Standard form is Ax+By=C. You can pull the slope by making the A negative and putting it over B: -A/B. To find your intercepts you replace either x or y sith 0 and solve from there. For example, 3x+2y=6 If you sub in 0 for y you get 3x+0=6 because 2 times 0 is 0. 3x=6 so you divide each side by 3 and you get x=2. This is useful when you want a simple graphing form.
Thanks! Could you describe point-slope form?
Point-slope form is y2 -y1 =m ( x2 - x1 ). You are given 1 point and the slope. For example, if you had y -5 = 2 (x-3). That is the simplified point-slope form. You have the slope which is 2 and the point (3,5)
That's it? Wow, that's a lot easier than I thought it was!
Yup. Well, you're all finished so head out that way. Good luck on that math test of yours!
