Answer:
A is your Answer
Step-by-step explanation: UR WELCOME
The rate of change of a line is regarded as the slope/ gradient (m) of the line
The slope/ gradient (m) of the line moving through points (x₁,y₁) and (x₂,y₂) is given as

On substituting the above values in the formula above we will have the slope to be

Therefore,
The rate of change of the line through (2,3) and (3,8) is 5
The slope is 2. y2-y1/x2-x1
Answer:
I think its, 5
Step-by-step explanation:
Becaus you take that number and its axcelerated calculation would be 5 in axis square root which is 3 and obviously 3+2 =5 so the wuarterining calculas is 5.
