10
11
12
y
27
a
11

In order for the data in the table to represent a linear
function with a rate of change of -8, what must be the
value of a?

0
a = 2
a=3
a = 19
a = 35

Answer 1

a = 19

Explanation:

Form a equation using y = mx + c form

(27) = (-8)(10) + c

27 = -80 + c

107 = c

y = -8x + 107

Substitute the x value to find a

y = -8(11) + 107

y = 19
