Write an equation in standard form of the line that passes through (3, 1) and has a y intercept of -2
aleksandr82 [10.1K]

Step-by-step explanation:

First of all, use substitution to find slope

(1) = m(3) - 2

3 = m3

m = 1

With both the slope and y int, you can write it in y int form

y = 1x - 2

Convert that to standard form

-x + y = -2

What is the leading coefficient of the polynomial x^5-198x+5x^12+4-2x^6 and explain why please
forsale [732]

The given expression is

x^5-198x+5x^{12}+4-2x^6

And we can also write it as

5x^{12}-2x^6+x^5 -198x+4

Leading coefficient is the number or the constant that is with the term with the degree. And here degree is 12, and the constant or the number that is with the term is 5 .

So the leading coefficient is 5 here.
