The equation of a line that goes through the point (x1,y1) and has a slope of m is
y-y1=m(x-x1)
so, given the point (-2,8)
x1=-2
y1=8
y-8=m(x-(-2))
y-8=m(x+2)
the equation is y-8=m(x+2) where m is the slope
or you could rewrite it to get y=mx+2m+8

Answer:
y = -5 
Step-by-step explanation:
<em>-</em><em>7</em> = <em>y </em><em>-</em><em>2</em><em> </em>
<em>y </em><em>=</em><em> </em><em>-</em><em>7</em><em> </em><em>+</em><em>2</em>
<em>y </em><em>=</em><em> </em><em>-</em><em> </em><em>5</em><em> </em>

Y=30x. 
Whatever the number of months is you times by 30, the amount she added each month. If she had started with a certain amount you would add that to the equation. Y is the total money in the account.
        
                    
             
        
        
        
Using the z-distribution, it is found that the 95% confidence interval for the proportion of sales that occured in December is (0.1648, 0.2948).
<h3>What is a confidence interval of proportions?</h3>
A confidence interval of proportions is given by:

In which:
 is the sample proportion. is the sample proportion.
In this problem, we have a 95% confidence level, hence , z is the value of Z that has a p-value of
, z is the value of Z that has a p-value of  , so the critical value is z = 1.96.
, so the critical value is z = 1.96.
The sample size and the estimate are given by:

Hence:


The 95% confidence interval for the proportion of sales that occured in December is (0.1648, 0.2948).
