Write the equation of a line parallel to y= 2x + 2 that passes through the point (-1,-7). Show your work.
oksian1 [2.3K]

Answer:

\large\boxed{y=2x-5}

Step-by-step explanation:

The slope-intercept form of an equation of a line:

y=mx+b

Parallel lines have the same slope. Therefore if given line is

y=2x+2

then the slope of our line is m=2.

We have the equation:

y=2x+b

The line passes through (-1, -7). Put the coordinsted pf the point to the equation:

-7=2(-1)+b

-7=-2+b          <em>add 2 to both sides</em>

-5=b\to b=-5

Finally:

y=2x-5

​it's believed that as many as 2222​% of adults over 50 never graduated from high school. we wish to see if this percentage is t
jenyasd209 [6]

The given values are:

p =  22% = 0.22

Zc = 1.645 at 90% confidence level.

margin of error, E = 0.04

 

The formula we can use here is:

E = sqrt(pq/n) * Zc

 0.04 = sqrt(0.22*(1-0.22)/n)*1.645

n = (0.22*(1-0.22))*(1.645/0.04)^2

n = 290.22

 

hence minimum sample size = 290
