Answer 1

Answer:

Step-by-step explanation:

y = m x + b

Given the slope of the line m and one point P1 = (x1,y1) through which the line passes, we can formulate the equation as as:

(y- y1)/(x-x1)= m

We have written this equation in a form which makes it clear that the slope calculated between any point (x,y) on the line and the given point P1 is the same. However, the relationship generally gets simplified algebraically to:

y = m (x-x1)+ y1

This form is tidier, but conceals the simple truth behind how the equation was crafted, namely as a statement about the slope of the line.
