And thus the table becomes:\begin{array}{lcccccc}\hlinex\ \ \ &\ 0\ &\ 1\ &\ 2\ &\ 3\ &\ 4\ &\ 5\ \ \\\hliney\ \ \ &\ 7\ &\ 5\ &\ 3\ &\ 1\ &\ -1\ &\ -3\ \\\hline\end{array}Then, use these pairs of x and y coordinates to graph the line
in a Cartesian coordiante system. The x and y values are from 0 to 7 so the range for the plot axes could, for instance, be {-5, 10} in range and all number pairs from the table will be included as points. And the graph increases for a unit with the increment of x-axis for every step. So, it's equivalent to say the y-values for x = 0 to 5 are: 7, 5, 3, 1, -1 and -3, respectively.
Explanation
## Step1: Understanding the problemWe are given a straight line given with the equation
. We have to complete the table given with this equation for values of x from 0-5. That means, we should plug-in values of x into the equation one-by-one and return corresponding y values. ## Step2: Defining the formula for calculationsThe formula to use for calculating y is from y's equation of ###
## Step3: Solving for each xUsing the formula defined in step 2, We will then substitute each x-value into the equation
to obtain corresponding y values.
