What is the slope?
What is the meaning of the slope in context if x is the number of weeks and y is the amount of money in your account?
To find the slope of the given points, we can use the formula for slope, which is (change in y) / (change in x).
For the first two points (-4,14) and (-2,8), the change in y is (8-14) = -6 and the change in x is (-2-(-4)) = 2. Therefore, the slope is -6/2 = -3.
For the last two points (3,-7) and (5,-13), the change in y is (-13-(-7)) = -6 and the change in x is (5-3) = 2. Therefore, the slope is -6/2 = -3.
In the context where x is the number of weeks and y is the amount of money in your account, the slope represents the rate of change of money in the account per week. A negative slope (-3 in this case) indicates that the amount of money in the account is decreasing by $3 per week.
