so if it is perpendicular, your slope should be  -1/5
so 2.

Thank you @melodysim

The slope of y = 5x + 4 is 5 or 5/1


Flip the fraction  5/1 ---> 1/5

Flip the sign: +1/5 ---> -1/5


So the perpendicular slope is -1/5 and only choice 2) has this slope

Oh okay gotcha !
The equation of line AB is y = 2x + 4. Write an equation of a line parallel to line AB in slope-intercept form that contains point (3, -2). (4 points)
Question 4 options:
	1)	y = -2x + 4
	2)	y =   x -  
	3)	y =   x -  
	4)	y = 2x - 8
