-5/8n= -0.4
Divde both sides by -5/8
n = 0.64
C) and E) because for X = -1 and X= 1 the functions f(x) and g(x) they have the same values.
Y=mx+b
m=slope
given
y=4x+5
m=4=slope
2.
for the points (x1,y1) and (x2,y2), the slope of the line passing trhough those points is (y2-y1)/(x2-x1)
given
(1,6) and (3,10)
slope=(10-6)/(3-1)=4/2=2
function 1 slope is 4
function 2 slope is 2
4>2
the first one has greater rate of change
Two intersecting lines will form 2 pairs of congruent vertical angles. Congruent angles have the same angle measure and vertical angles are opposite angles formed by two intersecting lines. Hope this helps.
