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
15.5 31 days in January and he loses .5 per day so the equation would be 31x.5 which equals 15.5
