Aline passes through the point -9, 5 and has a slope of negative 2/3 write an equation in slope intercept form for this line

You are given the slope
-2/3
y = -2/3x + b
solve for b by plugging in the point
5 = -2/3 (-9) + b
5 = 6 + b
subtract 6 from both sides
-1 = b

the equation
y =  -2/3x -1

Hope this helps :)
