Can you calculate the slope of that line?Anna55 said:...perpendicular against the line x-y+1=0
Decide the equation for the line which goes through origo and are perpendicular against the line x-y+1=0
Anna55 said:Please explain how to solve this.
Anna55 said:x-y+1=0
y=x+1
The slope is 1. Correct
1(x)= -1 You should use symbol m for representing the slope here (symbol x is already used as a variable, in this exercise)
x= -1 This is the correct slope for the perpendicular line
y = -x This final answer is correct
Is my working out correct?
