Key Formulas
Distance in the Coordinate Plane
Distance = , if you’re measuring the distance between the points (x1,y1) and (x2,y2).
Midpoint Between Two Points
Midpoint = (, ), where the endpoints of a line segment are (x1, y1) and (x2, y2).
Point-Slope Form of the Equation of a Line
y – y1 = m(xx1)�, where m is the slope of the line and (x1,y1) is a point on the line.
Slope-Intercept Form of the Equation of a Line
y = mx + b, where m is the slope of the line, and b is the y-intercept of the line. Both m and b are constants.
Slope of a Line
Slope = , where two points on the line are (x1, y1) and (x2, y2).
Standard Form of the Equation of a Circle
(xh)2 + (yk)2 = r2, where (h, k) is the center of the circle and r is the radius. When centered at the origin, the equation simplifies to x2 + y2 = r2.
Standard Form of the Equation of an Ellipse
= 1, where the ellipse is centered at (h, k) and has a horizontal axis of length 2a and a vertical axis of length 2b.
Standard Form of the Equation of a Parabola
y = a(x – h)2 + k, where a, h, and k are constants.
Standard Form of the Equation of a Hyperbola
= 1, where a, b, h, and k are constants. When centered at the origin, the equation simplifies to = 1.
