Kaya is saving money at a rate of $30 per month. Edgardo is saving money at a rate of $35 per month. They both started saving at the same time. If you were to create a table of values and graph each function, what would be the slope of each graph?
let Kaya's savings be 30x and Edgardo's savings be 35x
If they both started saving at the same time:
f(x)=30x
f(x)=35x
Now, sub in values for x in to the function starting with 0. Subtract y2-y1 and x2-x1 for both functions.
For slope: m=y2-y1/x2-x1
so your result will be m=30/1=30 for f(x) = 30x
and m=35/1=35 for f(x) = 35x
so the slopes are m=30 and m=35 respectively!
