Answer:
y = -5x + 5
Step-by-step explanation:
Let the equation of the line be: y = ax + b.
The given points should satisfy the equation.
Substituting the points in the equation we get the values of 'a' and 'b'.
The first point is: (1,0)
⇒ 0 = a(1) + b ⇒ 0 = a + b
⇒ b = -a
(2, -5) is another point. Substituting this we have:
-5 = a(2) + b = 2a - a = a
⇒ a = -5
⇒ b = -a = 5.
Therefore, the equation of the line becomes y = -5x + 5.
You would just add up all of the values and divide by six to get the average
Answer:2
Step-by-step explanation:
Answer:
The given equation 3x^2-4x+21 has no factors.
Step-by-step explanation:
We need to factorize this equation.
For factorization we split the middle term such that their sum is equal to middle term and product is equal to product of first and last term of the given expression.
in Our case : 63x^2
We need to find two factors of 63x^2 whose sum is equal to -4x
Factors of 63= 1,3,7,9,21,63
1* 63
3*21
7*9
None of the above factors sum is equal to -4.
So, the given equation 3x^2-4x+21 has no factors.
