This site can help you. https://www.desmos.com/calculator If two lines are perpendicular then the product of their slopes is -1.

really

anonymous · Answer

You have to use the equation y = mx + b 
m is the slope number 
You insert your 0,4 (x,y) cordinates for the y and the x of the equation and then you solve

@allyr I think it would be y= mx + 4. is that right?

confluxepic · Answer

You can get two points by finding the x-intercept and y-intercept.

i really don't understand

anonymous · Answer

I would say yes but I am only certainly familiar with the equation of a line that is parallel to another and passes through a point so I don't know for sure about it being perpendicular
