Graph equation for a circle
WebFor example, graph the circle with equation (𝑥 – 7) 2 + (y – 4) 2 = 4. In this example, the centre is (7, 4). We first plot this centre coordinate by finding 7 on the 𝑥-axis and 4 on the y-axis. To draw the circle, it helps to form a … WebOct 31, 2024 · Graph a circle given an equation that is not in standard form. If we were to expand the equation in the previous example and gather up like terms, instead of the easily recognizable \((x+2)^2 + (y-1)^2 = 4\), we'd be contending with \(x^2 + 4x + y^2 - 2y + 1 = 0.\) If we're given such an equation, we can complete the square in each of the ...
