Slope is change in y over change in x.
Change in y is -9
Change in x is +12
So -9/12 or -2/3
Answer -2/3
Answer:
-5
Step-by-step explanation:
do it chronologically so
7-3=4
4-10= -6
-6+9= 3
3-8= -5
The function would be f(x) = 40x + 4.
It's plus 4 because it starts counting after the 4 kilometers already happened.
It's 40x because that's the rate of change (km/h) and the x represents the hours.
f(x) basically means y, but in functions you use f(x).
Hope this helps :)
