Answer:
y = -4x + 36
Step-by-step explanation:
First, find the slope by calculation (y2-y1)/(x2-x1), you should get -8/2, or -4.
Next, plug the points into the equation y-y1 = slope(x-x1), getting y-28 = -4(x-2).
Simplify the equation and you get y =-4x + 36.

7x4=21
4x4÷2=8
Answer:
C
Step-by-step explanation:
By observation, and inspecting the 2 given points closely, we can immediately see that both points have y = -2 as common y-ordinates .
This means that the horizontal line y =-2 joins these 2 points.
Answer C is correct.
Answer:
The local minimums is the point of a function with lowest output (Locally). In this case, the values at which the function has a local minimum is: (-2, -3) and (4, -5).
All local minimum values of f are: (-2, -3) and (4, -5), given that the point (1, -1) is a local maximum.
Answer:
an = -9 + 7( n - 1)
Step-by-step explanation:
an = first term + difference (n-1)
First term = 9
Difference = -2 - -9 = -2 + 9 = 7
an = -9 + 7( n - 1)
You can check this by substituting the values in.
a1 = -9 + 7(0) = -9
a2 = -9 + 7(2) = -9 + 7 = -2
a3 = -9 + 7(3) = -9 + 14 = 5
