Question

You are gathering data about factor Y and factor X. A graph of your results in a straight line. What does this tell you about the relationship between y and x? What would the slope of this line represent? Explain your answers in terms of y and x

Answer 1

Step-by-step explanation:

a straight line graph shows a linear relationship between and x and y, where if gradient is positive then it's a positive linear relationship (where when factor increases the other would also increase). if the the gradient is negative then it's a negative linear relationship where when factor decreases the other would also decrease.

the slope of the line is the gradient which can be determined using the equation,

gradient = y difference ÷ x difference

respective to which factor is presented by each axis.

hope it helps. :)
