The equation
describes a linear relationship with a slope of -37. See the graph attached.
When expanded and simplified, the equation becomes
, which further simplifies to
.
This is a downward-sloping line with a y-intercept at (0, 68) and a slope of -37. The line crosses the y-axis at 68, indicating the initial y-value when x is zero. As x increases, y decreases at a rate of 37 units for each unit increase in x.
The graph is a straight line, illustrating a consistent and negative linear relationship between x and y.
