Answer :
#Rate of change
Rate of change is slope
If two points be (x1,y-1) and (X2,Y2) then
- Slope=m=y_2-y_1/x_2-x_1
If a line be ax+by+c=0
- m=-a/b
#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
