Answer:
i gotchu dude
Step-by-step explanation:
For example, a common equation, y=mx+b y = m x + b , is a linear function because it meets both problems with x and y as variables and m and b as constants.
the steps for writing a linear exp. are
1.) Identify the y-intercept from the graph.
2.)Choose two points to determine the slope.
3.)Substitute the y-intercept and slope into slope-intercept form of a line
.nowww to determine if an equation is a linear function without graphing, you will need to check to see if your function has the characteristics of a linear function. Linear functions are first-degree polynomials. Check that the y, or independent variable, is by itself on one side of the equation.
there are different ways to write linear functions like
1.)f(x) = mx + b (The "slope-intercept" form),
2.)y - yo = m(x - x0) or, equivalently, f(x) = y0 + m(x - x0) (The "point-slope" or "Taylor" form), and.
3.)Ax + By = C (The "general form") which defines y implicitly as a function of x as long as B 0.
hope this helped ;P
