Answer: A.)The response variable is the amount of activity the patients were able to do after surgery, and the explanatory variable is the type of spinal surgery.
Step-by-step explanation:
The response variable focuses on the question in a study or an experiment while the explanatory variable is the one which explains the changes in that variable.
Here response variable is the amount of activity the patients were able to do after surgery while the explanatory variable will be spinal surgery type
Option A is correct
okay. the point has an x and y value. place them into the equation.
1=m(1)+b
m=slope, and theequation tells you that slope is 7.
1=7(1)+b
now you need to figure out what b is.
1=7(1)+b
^
1= 7 +b
-7 -7
---------------
-6=B
b is 6. now place it into the equation, replacing the x and y values back.
y=7x-6.
write 7 and 6 in the boxes (the negative for the six has already been provided)
Answer:
y = -1/4x - 2
Step-by-step explanation:
Step 1: The y-intercept is on the y-axis line. The y-intercept in this graph is -2.
Step 2: To find the slope. The line is going downwards so that helps us know that the slope is going to be negative. You want to get the bottom point to the top. So move upwards 1 time and move 4 times to the left.
Step 3: Now just put everything together.
Answer:
Find the solution(s) to y=x+ 3 and y = 2x – 2. Find some ... Without graphing, determine whether each system of equations will have no solution, one solution, or ...
