Answer:

Step-by-step explanation:
To find the distance between any two points, we can use the distance formula.
The distance formula is:

Let (2,8) be x₁ and y₁ and let (7,7) be x₂ and y₂. Thus:

Simplify:

Square:

Add:

And that's our answer :)

Answer:
y= -2x+9
Step-by-step explanation:
The equation will be written this way :
y= m*x+c
- m is the slope
- c is a constant
- m =( f(4)-f(2))/(4-2)=(1-5)/2= -4/2 = -2
- y = -2x+c
- replace x and y by the coordinates of a point to get c
- 1= -2*4+c
- c = 9
y = -2x+9
