To draw a quadratic graph from an equation: Add up the terms of the quadratic expression, a column at a time, to find the value of 𝒚. The value of 𝒚 when 𝒙 = -4 is found by adding the ...

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 ...
