What are linear and nonlinear regression?
A linear equation is an equation that in math. It is a line. Liner equations have no X2. An example of a linear equation is x-2 A linear equation also equals y=mx+b. It has a slope and a y-intercept. A non-linear equation is also an equation in math. It can have and x2 and it is not a line. An example is y=x2+3x+4 Non linear equations can be quadratics, absolute value or expodentail equations.
What is a linear graph?
A linear graph is a model of a straight line on the X and Y axis. It represents the equation y=mx+b. A liner graph has a slope. A liner graph cannot be equaled to 0.
How would you know if the equation is liner by just looking at the equation?
No powers also, no x times y i.e. xy = 1 is not linear
Is y equals -3 a liner equation?
Yes, it is a linear equation with no slope. The graph is a straight line (parallel to the x-axis) that passes through the y-axis, at {0,-3}
Solve the system of liner equation by graphing 2x plus y1and y2x plus 1?
Without any equality signs the given expression can't be considered to be straight line equations.
