We use substitution to calculate the values. We replace the value of x for different numbers and record the resulting y value. These coordinates can then be plotted on a graph. Step 1 – The x ...
All the coordinates have equal values for \(x\) and \(y\). This is shown by the points on the line such as (10, 10) and (-4, -4). Graph A is \(y = -x\). All the coordinates have \(x\) and \(y ...
