Ответ:
lines are perpendicular
Step-by-step explanation:
If 2 lines are perpendicular then the product of their slopes = - 1
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
(1)
y =
x - 1 ← is in slope- intercept form
with slope m =
(2)
3y = - 4x + 6 ( divide each term by 3 )
y = -
x + 2 ← in slope- intercept form
with slope m = -
Then
Thus the 2 lines are perpendicular to each other
