Step-by-step explanation:
The 1st one isn't as clear in the picture, but it looks like the ends of each line overlap the each other.
Answer:
Step-by-step explanation:
The point slope form is expressed as
y - y1 = m(x - x1)
Where
m represents slope
Slope, m =change in value of y on the vertical axis / change in value of x on the horizontal axis
change in the value of y = y2 - y1
Change in value of x = x2 -x1
y2 = final value of y
y 1 = initial value of y
x2 = final value of x
x1 = initial value of x
The given points are (2,6) and (-1,3)
y2 = 3
y1 = 6
x2 = - 1
x1 = 2
Slope,m = (3 - 6)/(- 1 - 2) = - 3/- 3 = 1
To determine the equation, we would substitute x1 = 2, y1 = 6 and m= 1 into the point slope form equation. It becomes
y - 6 = x - 2
3(y+4)-3=y+(y+5)
3y+9=2y+5
1y+9=5
1y=-4
y=-4

You just keep multiplying the current value by 0.95 to get next year's value.
