This is assuming the sum of the two angles produces a straight line, or a 180° angle. Since the given angle is 121°, angle w must be 180-121, which is 59<span>°.</span>
Find the slope of the line using the equation (y1-y2)/(x1-x2), which is change in rise over change in run. use any two points, for example (2,-2) and (3,-1). using the formula, (-2-(-1))/(2-3) is the rate of change, giving you -1/-1 as the slope, which is -1. the rate of change is -1.
moves left 1 unit and up tow units any thing on the inside of the brackets means it will move left or right + menas left - means right on the outside it will move up or down - menas down + means up
