Answer:
the degree is 2
Step-by-step explanation:
because when you distribute x - 2 to x+3 = x^2 - x - 6. When you see an exponent in a trinomial that's the degree. If it's polynomial and has multiple exponents the degree is the highest number of the exponents.
Example:
2x^5 + x^3 - 4x + 1
The degree of this polynomial is 5 since it's the highest exponent number.
Answer:
#9 slope is -2, y int is 3
#10 slope is 3/4, y int is 0
The rule of the linear equation which is 'y is three more than twice x' can be translated into y = 2x + 3. Thus, we simply use the points and subtitute it to the y and x variables.
1st point: (-1, 1)
1 = 2(-1) + 3
1 = -2 + 3
1=1
2nd point: (0, 3)
3 = 2(0) + 3
3 =3
3rd point: (-1/3, 7/3)
7/3 = 2(-1/3) + 3
7/3 = -2/3 + 3
7/3 = 7/3
All points prove the equation satifsfies the set of coordinates.
