Answer: a) $y=-3x+3$

Step-by-step explanation:

The equation of a line passing through a point (a,b) ans has slope m is given by :-

$(y-b)=m(x-a)$

Similarly, the equation of a line passing through a point (-1,6) ans has slope -3 is given by :-

$(y-6)=-3(x-(-1))\\\\\Rightarrow\ y-6=-3(x+1)\\\\\Rightarrow\ y-6=-3x-3\\\\\Rightarrow\ y=-3x-3+6\\\\\Rightarrow\ y=-3x+3$

Hence, the correct option is : a) $y=-3x+3$

Hunter-Best [27]

Answer:

A political strategist wants to test the claim that the percentage of residents who favor construction is more than 30%, so then that represent our claim and needs to be on the alternative hypothesis.

Based on this the correct system of hypothesis are:
