This video teaches us the method to write an equation in slope intercept form and to graph it. The equation of line is y = mx + c. m is the slope and c is the y intercept or the point where it crosses the y axis. Let us find the equation of line if it crosses (8,6) and m=1/2. Substituting the values of x,y and m we get 6=(8)(1/2)+b. Simplifying we get b=2. Substituting the values in the equation of line, we get y = m/2 + 2. Suppose we want to find the x coordinate of a point on the line given its slope(1/2), y coordinate(6) and y intercept(12). Substituting in the equation of line, we get 6 = (1/2)x + 12. Simplifying we get x=12. This finishes the video.
