Step-by-step explanation:
Slope can be represented as rise over run (change y-values over change in x-values). Since the y-value is changing by -2 every time the x-value is changing by 2, the slope of the line must be .
In slope-intercept form ,
represents the slope of the line,
represents the y-intercept, and
represent the coordinates of any point the line passes through.
To find , substitute
and any point the line passes through.
Using (1, 0) from the table:
Thus, the equation of this line is
