Find the Equation of the Line

Question 1:

With gradient 2 5
through the point
(5,-9)
y = 2 5 x11

Question 2:

With gradient 4
through the point
(4,1)
y =4 x15

Question 3:

With gradient -1
through the point
(-2,1)
y = x1

Question 4:

With gradient 3
through the point
(-5,-8)
y =3 x+7

Question 5:

With gradient 1 2
through the point
(-6,7)
y = 1 2 x+10

Question 6:

With gradient 1
through the point
(-2,1)
y = x+3
