The angle it makes with the positive x-axis is:The angle a line makes with the positive x-axis, measured anticlockwise, is its:The tangent of the inclination of a line is called its slope or:Lines parallel to the x-axis have an inclination of:The inclination of a vertical line is:The slope of a line is denoted by which letter?The distance of a point from a line is the length of which segment?For which inclination is the slope of a line not defined?What is the slope of the x-axis?Three points lie on a line when the area of the triangle they form is:Three points that lie on the same line are described as:Two lines drawn in a plane are found to be either parallel or:The angle between two lines is discussed in terms of their:The inclination of a line may be described as acute or:An equation of the form Ax + By + C = 0 is called the general equation of a:In the general equation of a line, A and B must not both be:Why must the two points used to compute a slope have different x values?A line with slope m and y-intercept c passes through which fixed point?The line is described as the simplest figure in which branch of geometry?
