Answer:
y = -
x + 2
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 + 1 ← 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 (8, - 2) into the partial equation
- 2 = - 4 + c ⇒ c = - 2 + 4 = 2
y = -
x + 2 ← equation of perpendicular line
120 * .08= 9.6
120 - 9.6= 110.4
Answer:
helloooooo
Step-by-step explanation:
The first, second, fourth, and fifth statements are true. The third statement is false because polygons can have congruent sides but noncongruent angles, and this is easiest to exemplify using a rhombus, a four-sided figure with identical side lengths but different angle measures.
