Find the Equation of the Line

Question 1:

With gradient 4
through the point
(7,-7)
y =4 x35

Question 2:

With gradient -5
through the point
(2,-6)
y = 5 x+4

Question 3:

With gradient -4
through the point
(0,-6)
y = 4 x6

Question 4:

With gradient 3
through the point
(6,-3)
y =3 x21

Question 5:

With gradient 3 4
through the point
(-1,6)
y = 3 4 x+ 21 4

Question 6:

With gradient 1 5
through the point
(-5,10)
y = 1 5 x+9
