2)
a*2 + b = 26;
a*(-4) + b = -16;
then, a*6 = 42 => a = 7 => b = 26 -14 => b = 12;
from table, 7*9 + 12 = 63 + 12 = 75, correct;
7*(-8) + 12 = -56 + 12 = -44, correct;
slope = ( -44 + 16) / ( -8 + 4) = ( - 28) / (-4) = 7 = a;

( B ) . No; the input value x = - 5 pairs with two output values.
Answer:
15$
Step-by-step explanation:
this is because if you use our formula of I= prt
we can substitute our varibles for our equation
I= 300 x 0.05 x 1
we turn 5 in 0.05 to represent out rate, due to this our rate would have to be Simplified into a percent then a decimal
after this if we now proceed through our equation we will get
I = 300 x 0.05 x 1
I = 15
