Step-by-step explanation:

4n - 7 = 29
That's the equation :)
You can use any variable; doesn't have to be n.
If you want to solve for the variable, then it would be 5.5
Answer:
y = -4x - 16 or y +4x + 16 = 0
Step-by-step explanation:
Gradient (m) = -4
Equation of a line given gradient and one point=
y - <em>y </em>= m(x - <em>x)</em><em> </em>where (<em>x </em>, <em>y </em>) are the coordinates of the point.
Substituting...
y -(-4) = -4(x -(-3))
y + 4 = -4(x + 3)
y + 4 = -4x - 12
y = -4x - 12 - 4
y = -4x - 16 or y +4x + 16 = 0
