The line has a negative trendSo the slope is - ⅘
The y intercept is at 0, -3
So the equation for the line is……
Y = -⅘X - 3

The line has a positive trend So the slope is ²⁄₁ = 2
The y intercept is at 0, 1
So the equation for the line is……
Y = 2X + 1

The y intercept is at 0, -1
So the equation for the line is……
Y = -⅔X - 1

YY = ½X + 6
Y = ½X + 0
Y = ½X - 4
