Its a function if there are different numbers as each x value but if there are multiple of the same number in the x value it isn't a function
Answer:
(2a - 
)(2a + )
Step-by-step explanation:
4a² - 
← is a difference of squares and factors in general as
a² - b² = (a - b)(a + b) , then
4a² -
= (2a)² - ( )²
= (2a - )(2a + )
Hi,
Your y=MX+b equation would be y=20/81x+10
Hope this helps!
Y - y₁ = m(x - x₁)
y - 5 = -8(x - 2)
y - 5 = -8(x) + 8(2)
y - 5 = -8x + 16
<u> + 5 + 5</u>
y = -8x + 21
