The line through (-1,-1)and (2,0) has slope, %289-%28-1%29%29%2F%282-%28-1%29%29=highlight_red%2810%2F3%29.
'
The desired line perpendicular to it must have slope m%2810%2F3%29=-1,
highlight_red%28m=-%283%2F10%29%29.

Using point-slope form for a linear equation and the required point and slope, -%283%2F10%29%28x-1%29=y-3
y=-%283%2F10%29x%2B3%2F10%2B3
highlight%28y=-%283%2F10%29x%2B3%263%2F10%29
