The equation tells you the line has a y-intercept of -2 and a slope of -0.5. This means it has an x-intercept of -4.

All values of x less than -4 will give positive values for y.

All values of x greater than -4 will give negative values for y.

The graph and a table of some values are shown in the attachment.
