Question

Do you know how to find rate of change? X&Y intercepts? Zeros?

Answer 1

#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
