The answer in the procedure
Step-by-step explanation:
Let
m1 and m2 > the slopes of the lines constructed
we know that
If two lines are perpendicular, then the product of their slopes is equal to -1
therefore
To verify if the lines constructed are perpendicular
Multiply their slopes
if m1*m2=-1 > the lines are perpendicular
Ответ:
The slope is -2, and the y-intercept is 12
