Answer:
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
y = - 2x + 2 is in this form with slope m = - 2
given a line with slope m then the slope of a line perpendicular to it is
= - = - =
the point (0, 1 ) is the y- intercept ⇒ c = 1
y = x + 1 ← equation of perpendicular line
