Answer:
y = - x + 5
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 slope- intercept form
with slope m = 2
Given a line with slope m then the slope of a line perpendicular to it is
= - = - , thus
y = - x + c ← is the partial equation
To find c substitute (4, 3) into the partial equation
3 = - 2 + c ⇒ c = 3 + 2 = 5
y = - x + 5 ← equation of perpendicular line

Answer:
Each line segment joining a vertex of ABCD to the corresponding vertex in the image is perpendicular to the line of reflection, EF. That is, the lines intersect at a 90 degree angle.
The book cost 28.50 + 10%. Take 28.50 x .10 = 2.85 + 28.50 = 31.35 students get a 35% discount take 31.35x.35=10.97 now subtract 31.35 -10.97= 20.48 they have 21.00 dollars to spend after buying the book they .52 cents left.
