HOW TO FIND SLOPE AND Y INTERCEPT FROM AN EQUATION. The slope-intercept form of a line is : y = mx + b. where m is the slope and b is the y-intercept. Slope (m) = Rise / Run = Change in
Find the slope and y-intercept of the line : 3x - 9y + 3 = 0 Solution : Write the given equation in the form y = mx + b. 3x - 9y + 3 = 0. Add 9y to each side. 3x + 3 = 9Y. Divide each side by 9. (3x + 3) / 9 = y. 3x/9 + 3/9 = y. x/3 + 1/3 = y (or) y = x/3 +
What our customers say
Damn! The app is great again. This is very helpful especially when you want to find out the answer but students don't learn how they do it, love this app so much. In a word itâ€™s absolutely awesome! It has mind blowing calculator, math solving from pic, awesome explanations for maths and history facilities.
It also have a calculator but different from all,because it shows the steps so everyone can understand easily, this app is actually helpfull especially if you actually want to learn how to do the math it explains it really well, it know wich exact problem I'm talking about and it the picture ability is very useful.
This app completely eliminates the computation! Would recommend to friends. This app works very well and makes solving any math problems a breeze! It makes solving variables easy too, sO, THANK YOU SO MUCH.
