Answer:
y = -2x + 6
Step-by-step explanation:
y = mx + c
m = (2-4)/(2-1) = -2/1
m = -2
y = -2x + c
When x = 1, y = 4
4 = -2(1) + c
c = 4 + 2 = 6
y = -2x + 6
Answer: The slope is -32
Explanation:
Start with the slope formula:
m= (y2 - y1) / (x2 - x1)
Substitute point values in the formula
m = (-25 - 7) / (85 - 84)
Simplify each side of the equation
m= (-25 - 7) / (85 - 84) = -32/1
Solve for slope (m)
m= -32
Answer:
The average rate of change is 4
Step-by-step explanation:
To find the values of y when x = 0 and when x = 2, we can graph the equation using a graphing calculator.
Looking at the graph, we can see that when x = 0 y = 5 and when x = 2 y = 13
Now that we have two points (0,5) and (2,13) we can find the rate of change
To find the rate of change we use this equation: 
Let's input the values from our two points

Simplify:
= 4
C should be the correct answer
