Answer:
Option C is correct.
The equation of line graphed is, 
Step-by-step explanation:
Point slope form: The straight of line in the form of :
......[1] where m is the slope.
Consider two points from the given graph:
(0, 0) and (2, 1)
First calculate slope:
Slope(m) = 
Substitute the given values we have;
Substitute the given values m and (0,0) in [1] we have;
Simplify:
therefore, the equation of line graphed is,
Answer:
an = -2 -3(n-1)
Step-by-step explanation:
an = a1+(n-1) d
a1 =-2
d = -5--2
d = -5+2
d=-3
we are decreasing by 3 each time
an = -2 + (n-1) * -3
an = -2 -3(n-1)
Answer:
see explanation
Step-by-step explanation:
Given x and y are in proportion then the equation relating them is
y = kx ← k is the constant of proportion
To find k use an ordered pair from the table
Using (2, 10 ), then
10 = 2k ( divide both sides by 2 )
5 = k , thus
y = 5x ← relationship between x and y
