One well known form for writing linear functions is known as slope-intercept form, where xx is the input value, mm is the rate of change or slope, and bb is the initial value of the dependant variable.Equation formy=mx+bFunction notationf(x)=mx+bEquation formy=mx+bFunction notationf(...
If we know the slope of a line and its y-intercept, we define the line equation using the below equation. y=mx+c Here, the slope is m, and c is the y-intercept. So, we determine the slope of a line by converting the given line in the standard slope-intercept fo...

The first equation can be rewritten in slope-intercept form as y = 2x – 1, and the second equation can be rewritten as y = -x + 3. Graphing these lines on a coordinate plane, we can see that they intersect at the point (1, 2), which is the solution to the system. The initial...
and we want to predict y from x. Least Squares and Correlation The method we are going to use is called the least squares method. It takes a list of x values and y values (the same number of each) and calculates the slope and intercept of a line that best matches those values. See...
