Using the two coordinates you can find the equation ------------------------------------ Find slope first Slope [tex]= \frac{y2-y1}{x2-x1} [/tex] 0 - 3 = -3 ------- -4 - 0 = -4 -------------------------------------------------- Simplify -3/-4 3/4 ----------------------------------------------------------- Your slope is 3/4 and the Y-intercept as mentioned in the question is "3" ---------------------------------------------------------------------- So your equation is y = 3/4x + 3
