Answer:
y = -2x - 5
Step-by-step explanation:
The given slope, or m, is -2 and the given y-intercept, or b, is -5.
The y-intercept equation is y = mx + b, so by knowing this equation all you need to do is plug in the given slope and y-intercept
y = -2x - 5
Since August is the 8th month of the year, this means Kelli has called her grandmother 8 times so far since she calls her once a month
Since she calls her cousin every other month, Kelli has called her cousin 4 times so far because if she calls from January to August every other month, you would do 8÷2 because every other month = 2 months.
This means Kelli has called her grandmother 8 times
Therefore, 8+4=12.
Kelli so far has made 12 calls in total.
