Contour lines.
B
To determine if two sets of points are collinear, you can calculate the slopes of the lines formed by connecting the points in each set. If the slopes are equal, then the points are collinear. Another method is to calculate the area of the triangle formed by the three points in each set. If the area is zero, then the points are collinear. Lastly, you can use the determinant of a matrix method to check if the points lie on the same line.
One hundred points are equal to one carat.
since density equal to mass/volume then mass=density times volume mathematically mass=density *volume

An isobar is a line connecting two equal points of pressure.
On a Weather Map, the lines connecting points of equal temperature are called Isotherms.Similarly, the lines that connect points of equal barometric pressure are called Isobars.
