Answer:
1/2
Step-by-step explanation:
the rate of change is = the change in y/ the change in x
if the points are (2, 11) and (8, 14)
Rate of change = (14-11) / (8-2) = 3 / 6 = 1/2
The first one is D
The second one is true
X intercept: when y = 0
Or coordinates: (x, 0)
On the graph it’s: (-2, 0)
On the function, plug in y = 0
2x - 4(0) = 8
2x - 0 = 8, x = 4
The graph x intercept is -2
The function x intercept is 4
Solution: function x intercept is greater
I mean it depends what lake and where and the temperature, all variables you have to consider.
Y = -x - 9
-x -2(-x-9)=-5
-x +2x + 18 = -5
x + 18= -5
x= -23
-23+ y = -9
y= 14
