Coordinate Systems and Equations of Straight Lines Quiz

Slope = The measure of the steepness of a line Y-intercept = The point where a line intersects the y-axis Coordinate System = A system that uses coordinates to uniquely determine the position of points on a plane Equation of a Line = An expression that relates the x and y coordinates of points on the line

Parallel Lines = Lines that are always the same distance apart and never meet Intersection Point = The point at which two lines meet or cross each other Perpendicular Lines = Lines that intersect at a 90-degree angle Midpoint = The point that divides a line segment into two equal parts

$y = 2x + 3$ = Straight line $x^2 + y^2 = 25$ = Circle $y = \sqrt{x}$ = Half parabola $x^2 - 4x + y^2 - 6y = 12$ = Ellipse
