Answer:
Step-by-step explanation:
The points are (1, 3) and (-1, 1)
y2 = 1, y1 = 3, x2 = -1 and x1 = 1
Slope m = (y2 - y1)/(x2 - x1)
m = (1 - 3)/(-1 - 1)
m = -2/-2
m = 1
The question is
y - y1 = m(x - x1)
y - 3 = 1(x - 1)
y - 3 = x - 1
y = x - 1 + 3
y = x + 2
aApolynomial is an expression consisting of variables and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables.
There are 3 sets of polynomials; LINEAR, QUADRATIC and CUBIC
Linear: 
Quadratic: 
Cubic: 
Answer:
d) not proportional
Step-by-step explanation:
the rate of change between the first two pairs of x-and-y values is 12/3, between the second pair it is 21/3, and 15/3 between the last pair
4, 7, and 5 are all different values so there is not one constant of proportionality
