Write an equation for the line through (-3,2) and (6,1)
y(x)=
The slope is m = (1-2)/(6-(-3)) = -1/9
The equation is therefore
y = -(x/9) + b
Use the coordinates of either point to get the constant b.
2 = (3/9) + b
b = 5/3
y(x)=
The equation is therefore
y = -(x/9) + b
Use the coordinates of either point to get the constant b.
2 = (3/9) + b
b = 5/3
