<em>The average velocity of the object is multiplied by the time traveled to find the displacement. The equation x = ½( v + u)t can be manipulated, as shown below, to find any one of the four values if the other three are known.</em>
Y - 190 = 55(x - 2)....distribute thru the parenthesis y - 190 = 55x - 110....now add 190 to both sides y = 55x - 110 + 190..simplify y = 55x + 80 <== slope intercept form (y = mx + b)
