What are the y-values when x=-3 and x=5
um i dont knew how to find those
So, go to your graph and see when x=3, what the y-value is on the line.
y is -1?
Correct, y=-1 for both x=-3 and x=5
Do you know the slope formula?
y2-y1 average rate of change= ----- x2-x1
Or, do you know the property of the slopes of horizontal lines?
or like said, slope average rate of change between two points is just the slope of the secant line going through the points
so is it -1-(-3) 5-(-1)
No, it isn't. Make sure to put the points in the correct place in the formula.
no, y2 is -1 and y1 is -1
yes now what is it?
Note: x/ 0 = undefined 0/x = 0
And 0/-8 =?
so 0/-8 which is equal to?
so its 0
is that the answer?
thank you both of you
