3. Write the equation of a line in slope-intercept form that passes through (9, 4) and is
perpendicular to y = -3x - 2.
Equation:​

Respuesta :

⭐️- Remember that slope formula is y=mx+b

1. Know that the m is (-3)
2. 4=(-3)(9)+b
3. 4=(-27)+b
4. b=31
5. y=(-3x)+31
6. y=3x-31*

*whenever it is finding a perpendicular, you switch the signs; when it is finding a parallel, you leave it alone
