1. if the line passing through the point (5,2),
then
2=-3×5+b,
2=-15+b,
2+15=b,
then
b=17,
2. if the line passing through the point (-2,4),
then we have
4=-3×(-2)+b,
4=6+b,
4-6=b,
then
b=-2
then
2=-3×5+b,
2=-15+b,
2+15=b,
then
b=17,
2. if the line passing through the point (-2,4),
then we have
4=-3×(-2)+b,
4=6+b,
4-6=b,
then
b=-2

We have eq y=-3x+b
1. B(5,2)
Putting these values in eq
2=-3×(5)+b
2=-15+b
=> b=17
2. A(-2,4)
Putting these values in eq
4=-3×(-2)+b
4=6+b
=> b= -2
