The equation of a line that passes through the point (-1,-4) and has a gradient of 2 is y = 2x - 2
The equation of a line can be represented as follows:
y = mx + b
where
Therefore,
m = 2
y = 2x + b
-4 = 2(-1) + b
-4 + 2 = b
b = - 2
y = 2x - 2

3x - 5 = 10 or 3 × 5 - 5 = 10
y ÷ x - 4 = 14 or 36 ÷ 2 - 4 = 14
