The graph of the equation y2 = x3 2x2 + x looks like: Since many vertical lines cut this graph at more than one point, this is not the graph of a function. 1.2. Examples: Example 1.2. Linear Functions: A linear function is a function of the form f(x) = mx + b (where m ...
linear equation n. An algebraic equation, such asy= 2x+ 7 or 3x+ 2y-z= 4, in which the highest degree term in the variable or variables is of the first degree. The graph of such an equation is a straight line if there are two variables. ...
A linear functional errors-in-variables model with unknown slope parameter and Gaussian errors is considered. The measurement error variance is supposed to be known, while the variance of errors in the equation is unknown. In this model ... A Kukush,EO Maschke - 《Journal of Multivariate Analy...
A linear equation in slope-intercept form is written as {eq}y=mx+b{/eq} where {eq}m{/eq} is the slope of the line and {eq}b{/eq} is the {eq}y{/eq} intercept, the point at which the graph of the function crosses the {eq}y{/eq}-axis. A ...
