A linear graph.
A graph with an equation of the form:
a1x1 + a2x2 + ... + anxn + c = 0
where the ai are constants and xi are variable (i = 1,2, ... n) will be a straight line in n-dimensional space.
In 2-dimensions, the equation is more commonly written as ax + by + c = 0.
The key characteristic of the equation is that the variables appear as single terms, with power 1.
straight line
A scatter graph - unless the relationship is exact. If so, use a line (which need not be a straight line).
line graph
It depend what is the question of your graph. A normal graph consist an x-axis and a y-axis and the relationship is y against x. First you need to write the title,draw the axis,find a suitable scale on each axis and put a legand(which contain the information of your scale per boxes or rather 1cm or 2cm depending what type of graph paper you are using),use the table of data you have and start plotting, the line of the graph is normally draw freehand and line best fit(does not mean a straight line or must cross all the plot but a neat and nice straight or curve line) or otherwise a straight line connecting all the plot depending on type of graph you are drawing.

straight line
A straight line on a distance/time graph means that the speed is constant. In every unit of time the distance increases by the same amount.
linear: LINE example--- line non-linear: not a LINE example--- parabola The other possibility is a graph with a non-linear scale. First a linear scale will have each unit represent the same amount, regardless of where you are on the scale. A semilog scale, has a linear scale in the horizontal direction, and a logarithmic scale in the vertical direction. Exponential functions (such as ex & 10x), will graph as a straight line on this type of graph scale). A logarithmic or log-log scale, has logarithmic scales on both horizontal and vertical axis. Power functions (such as sqrt(x), x2 and x3), graph as a straight line on these scales. See Related Link

No. A linear equation is just one type of function.If you graph a linear equation, you get a straight line.A "function" on the other hand can take on many different forms: a straight line, a wave line (the sine function), a parabola, etc.No. A linear equation is just one type of function.If you graph a linear equation, you get a straight line.A "function" on the other hand can take on many different forms: a straight line, a wave line (the sine function), a parabola, etc.No. A linear equation is just one type of function.If you graph a linear equation, you get a straight line.A "function" on the other hand can take on many different forms: a straight line, a wave line (the sine function), a parabola, etc.No. A linear equation is just one type of function.If you graph a linear equation, you get a straight line.A "function" on the other hand can take on many different forms: a straight line, a wave line (the sine function), a parabola, etc.
