If you're referring to the Cartesian coordinate system, then it's 2 ordered pairs e.g. a straight line could be drawn between pairs (3, 5) and (2, 3) etc.
In order to draw a straight line, two unique ordered pairs are needed. This is because two unique points determine a line and an ordered pair represents a point.
You can only draw one straight line through any two given points.
A continuous linear function produces a straight line graph that can be extended indefinitely in either direction. If the two ordered pairs are plotted on a graph then a straight line can be drawn joining these points. If that line is extended beyond both ends then there are no set limits and the function becomes continuous.
I assume the ordered pairs are connected by straight lines. You can draw the corresponding figure (this helps you visualize it), then divide it into rectangles and triangles, calculate each partial area, and add everything up.
The answer is 'graph'
2 points
you draw straight lines with a ruler
2 points. However, the farther apart the 2 points the striaghter the line will be, unless you move the straight edge!!.
You would need basically a protractor and a straight edge.
draw a kite
I looked up and I think you use them to draw graphs but can use them to draw straight lines.
You can draw straight lines with the help of a ruler or anything with a straight edge.
