Can anyone solve this eqestion ??

a line passes through (5,-2) and is parallel to y=3x find the equation of the line ??

Use the standard format for you equation:

y = mx + b

The slope (m) must = 3 for the line to be parallel to y = 3x

Therefore y = 3x + b

Choose b so that y = -2 when x = 5. That will make it pass through the point (5, -2).
