Suppose g is a linear function such that g(2.5) = 13.6. If the slope of g is -3.2, what is g(8.8)? (Round your answer to two decimal places.)
If someone answers this, can I please get an explanation.
The function is linear , so it can be written in line form y = mx+b where m = slope = -3.2
y = -3.2 x + b you are given one point ( 2.5, 13.6) sub that in to get 'b'
13.6 = (-3.2)(2.5) + b to find b = 21.6
so g(x) = -3.2 x + 21.6 now put in x = 8.8 and calculate g(8.8)= ......
