Two points are enough to graph a linear function?
Answer:
>> There are three ways you can graph linear equations: (1) you can find two points, (2) you can use the y-intercept and the slope, or (3) you can use the x- and y-intercepts.
Example:
>> The first is by plotting points and then drawing a line through the points. The second is by using the y-intercept and slope. The third is applying transformations to the identity function f(x)=x f ( x ) = x .
Explanation:
>> Every linear graph is nothing more than a straight line so if there is any curvies in it, it's not linear. The other way to tell is look at its equation. If the equation can be shaped into Y = MX + B where M and B are numbers, then it's going to be a linear equation.
