Given slope m= -0.5

and the line passes through the point (x,y)= (2, -3)

the slope-intercept form of a line is

`y= mx+b`

from the above we know  ` m = -0.5 = (-1/2)` , so the line equation is 

`y= (-1/2)x+b` --------------(1)

we need to find the value of b, as the line passes through the point

(x,y)= (2, -3 ), then on substituting we get

`-3 =(-1/2)*(2)+b`

=> `b = -3+1 = -2`

so the equation of the line is

`y = (-1/2)x - 2`
