WebThe graphs of linear equations in two variables are straight lines. Linear equations may be written in several forms: Slope-Intercept Form: y = mx+ b In an equation of the form y = mx + b, such as y = −2x − 3, the slope is m and the y-intercept is the point (0, b). WebA quadratic equation in two variables, where a, b, andc are real numbers and a ≠ 0, is an equation of the form y = ax2 + bx + c Just like we started graphing linear equations by plotting points, we will do the same for quadratic equations. Let’s look first at graphing the quadratic equation y = x2.
