Answer :
The relationship between the variables in terms of direction form and strength.
Given :
the relationship of between the variables in terms of direction ( positive or negative slope ) , form (a straight line or a curve), and strength.
The straight line form with variables is :
y = mx + b is a straight line equation
here x and y are variables
m = slope
b = y - intercept
example :
y = 3x + 3
m = + 3 is a positive slope
y = -2x + 4
here
m = - 2 is a negative slope
