Indicate the equation of the line through (2, -4) and having slope of 3/5.
Nastasia [14]
Y = mx + b.....the m is for the slope , (2,-4)...x = 2 and y = -4
now we sub
-4 = 3/5(2) + b
-4 = 6/5 + b
-4 - 6/5 = b
-20/5 - 6/5 = b
- 26/5 = b

so ur equation is : y = 3/5x - 26/5 <== slope intercept form
or if u need it in standard form :
y = 3/5x - 26/5....(5)
5y = 3x - 26
-3x + 5y = -26...(-1)
3x - 5y = 26 <==standard form

OleMash [197]

Answer: d. There is no relationship between education level and smoking habits.

Step-by-step explanation:

The null hypothesis is the affirmation that two parameters or phenomena do not have a relation between them.

Here the parameters are smoking and having a bachelor's degree or higher education.

Then the null hypothesis says that those two things do not have any relation, this would imply that the probability of being a smoker does not depend on having a degree or not.

Then the correct option is d "There is no relationship between education level and smoking habits."
