Two points in a plane have polar coordinates (2.50 m, 30.0°) and (3.80 m, 120.0°). determine (a) the cartesian coordinates of these points and (b) the distance between them.

There is no graph to look at on here, but i shall explain them to you. a line graph is just in its title it’s a graph with a line running through the dots to show an increase or decrease. a bar graph is used to show how much or how little something is so a comparison. a scatter plot is used to graph points to tell the data. and i don’t know what a histogram is.
