The line is parallel so the slope is the same. So the slope = 2
Using a point-slope equation we have
 y-y1 = 2(x-x1)
plug in the points
y-1 = 2(x-(-2))
=> y = 2x + 4 - 1 
=> y = 2x +3

When the polynomial is written in standard form, what are the values of the leading coefficeient and the constant? 5x + 2 - 3x2
Elina [12.6K]

Answer:

The leading coefficient is -3

The constant is 2

Step-by-step explanation:

The standard form of a polynomial is the descending order, that means that it must be written according from its higher power, down straight to the coefficient with no variable.

Hence, the leading coefficient is the one that is next to the highest exponent of the polynomial, in this case: =3x2.

The second term is 5x

And the last is 2. the constant
