You forgot to provide the slope but here is how you do this
the slope 5 = (y2 - y) / (x2 - x) but we know that (x2, y2) = (-10, -5)
=> (-5 - y) / (-10 - x) = 5 --- multiply both sides by (-10 - x)
=> (-5 - y) = 5 (-10 - x)
=> (-5 - y) = -50 - (5)x --- add +5 to both sides
=> -y = (-50 + 5) - (5)x --- multiply both sides -1
=> y = 5x + 45 --- this will be your equation.

The answer to your question is 55.93
Answer: 0.0328
Step-by-step explanation:
Standard error is the standard deviation of the sampling distribution.
The formula to find the standard error is given by :-
,where n= sample size.
= Sample proportion.
Given : Of the 2266 high school students surveyed, 952 admitted to smoking marijuana at least once.
A study done 10 years earlier estimated that 45% of the students had tried marijuana.
i.e. Population proportion : p= 0.45
Sample size : n= 226
Sample proportion : 
Then , the standard error for this test will be :-
Hence, the standard error for this test= 0.0328
