Question

A) Assume a linear relationship between the variables Y and X , and that Y is the variable measured on the vertical axis while X is the variable measured on the horizontal axis. A straight line describing this relationship has a y-axis intercept of 10 and a slope of -1.25. What is the equation for this line?

B) Is the relationship between Y and X positive or negative? How can you tell just by looking at this equation?

C) Use the above equation to find the value of y for each of the values of x indicated below:

x = 0, y =

x = 4, y =

x = 8, y =

D) Sketch below a well-labeled graph and plot the three (x,y) coordinates you derived in part C above
