This week in math I learned how to solve for the x intercept and the y intercept in an equation.

For example with  3x+5y=20 to find the y intercept we would put a 0 in front of the 3x which would basically mean we could rewrite the equation as 5y=20 since we got rid of the 3x.

Then, we would divide 5y by 5 and we do the same thing on the other side so we divide 20 by 5, which gives us our answer that y=4. Our final answer is in coordinate form which is (o, 4) because the y intercept is the second number in the brackets.

To find the x intercept we would do the same thing, except get rid of all the numbers with y’s in the equation. Then once you put your answer in coordinate form, your answer would be the first number in the brackets. So (x, 0).

If you are trying to find an x^2 or y^2 and before you square root it it’s a positive number, you need to put two answers because if you multiply two positive numbers together they would equal a positive and if you multiply two negatives they would also equal a positive, so your coordinate number would have to be positive and negative.
