Respuesta :
The slope of the line represents that the remainder of the goal decrease by 8 for each card sold.
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the slope of the line and b is the y intercept.
Let y represent the remainder of goal and x represent the cards sold.
Using points (10, 875) and (50, 555) from the table:
[tex]slope(m)=\frac{y_2-y_1}{x_2-x_1}=\frac{555-875}{50-10}\\\\m=-8[/tex]
Therefore the slope of the line represents that the remainder of the goal decrease by 8 for each card sold.
