First, rearrange the equation into y = mx + b (slope-intercept) form. This is to clearly identify "m", the slope.Decide the equation for the line which goes through origo and are perpendicular against the line x-y+1=0
Here's a step-by-step example, using a different given line.Anna55 said:Please explain how to solve this.
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?
