No, Lily is not correct. This is because 16+3 does not equal 18. So to find N, you take 18 and subtract 16.
18-16=n
18-16=2
so n=2
16+2=18.
-- If two lines on a graph are parallel, then their slopes are equal.
-- If two lines on a graph are perpendicular, then their slopes are
negative reciprocals.
Answer:
D
Step-by-step explanation:
the equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b ) a point on the line
here m = 2 and (a, b ) = (- 2, 1 ) , then
y - 1 = 2(x - (- 2)) , that is
y - 1 = 2(x + 2)
The best estimate of the solution to this system of equations is about (23,14)
