The word linear means in a straight line. If the graph is a line, it is linear. Also, linear equations are of the first order; they contain a variable but not a square (or higher power) of a variable. If the equation contains x2 it is not linear.
The graph must be linear and pass thru the origin
A linear function would be represented by a straight line graph, so if it's not a straight line, it's nonlinear
By definition, if you graph the relationship between two variables and the result is a straight line (of whatever slope) that is a linear relationship. If it is a curve, rather than a straight line, then it is not linear.
Unfortunately the graph does not show.. But, i can tell you that business cycle is divided into: 1) introduction - start of the graph 2) growth - graph goes up 3) maturity - graph is static and slowly pointing doen 4)decline - graph starts to go down.. if your graph is this way, then the answer is yes..
-- The graph of a linear equation is a straight line. -- Any two points on a straight line are enough to completely specify the line, that is, to uniquely identify the line and tell you everything there is to know about it.
A linear function, of a variable x, is of the form ax+b where a and b are constants. A non-linear function will have x appearing in some other form: raised to a power other than 1, or in a trigonometric, or exponential or other form.
There is a dot on the graph
The slope tells you the object is travelling at a constant speed. If the position vs time graph is not linear, the slope tells you the average speed between the two points.
All the x's and all the y's in the equation must have no exponent (except '1').If you see an x2, or a square root of 'x' or 'y', or a y-1/2, or a y2, etc. then the graph is not a straight line.
No. It will tell you WHEN but not where.
to tell them why you made this graph
