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 ...

These two axes intersect at a perpendicular angle (meaning it's 90 degrees), which forms four quadrants that create a space to locate points and graph ... x-coordinate and a positive y-coordinate ...

Express the polar equation \(r=\cos 2\theta\) in rectangular coordinates. Find the maximum height above the \(x\)-axis of the cardioid \(r=1+\cos \theta\text{.}\) Sketch the graph of the curve whose ...
