Answer
a. The Output, y, is 8 plus the quantity 2 times the input, x. The Equation is y = 8+2x The table and the graph are attached below.
b. The set of ordered pairs (0,2)(1,4)(3,5)(1,8) doesn't represent a linear function
Work Step by Step
a. The Equation is y=8+2x because the output before any input was 8 and when the independent variable, the input increased by 1, the the dependent variable i.e. the output increased by 2 and so the slope is 2.
b. The ordered pair set doesn't represent a linear function because it doesn't pass the vertical line test as for every x value there is more than one y value.
