The basic slope formula is ymxb while the more complex point-slope formula is y-ylmx-x1. It is in y mx b In this formula m is the slope of the line and b is equal to the y intercept. When a line is given in point-slope form eqymxb eq line is expressed in terms of two quantities.
Let the slope 2 let the point 35 the standard form of y mx b becomes y 2x b now you take the point xy 35 that is on the line has to be on the line and replace x and y in the equation with it.
Similarly the form ymxa means slope m and y-intercept a. We will derive this formula using the equation for the slope of a line. Designing a graph from this equation is easy especially when values are simpler. Let us consider a line whose slope is m and whose y-intercept is b or 0b.
