#Rate of change
Rate of change is slope
If two points be (x1,y-1) and (X2,Y2) then
If a line be ax+by+c=0
#X and y inetercept
If a equation given y=mx+b
- To find x intercept put y=0
- To find y inetercept put x=0
#Zeros
To find the zeros spot out the x inetercepts
The x values of the x intercepts are the zeros
Answer:
Total Mark = 5c - a
Step-by-step explanation:
Total Mark = 4c - (a - c) = 5c - a
