The sample is the amount of people because not everyone is getting chosen
Step-by-step explanation:
2.6 is the aswer.
Why?take the 2 number after the decimal the estimate
Perpendicular lines have slopes that are opposite and reciprocal. Therefore, the line we are looking for has a -3 slope.
y= -3x+b
Now, we can substitute in the point given to find the intercept.
2= -3(4)+b
2= -12+b
b=14
Finally, put in everything we've found to finish the equation.
y= -3x+14
