One line is given by the equation:$y = x$ because it starts at the origin and has a slope of 1 (given by the 45 degree angle) The second line is given by:$y = -\frac{3}{9}x+3 = -\frac{1}{3}x+3$because its slope is -3/9 and its y-intercept is 3. Now solve for where they are equal:$x = -\frac{1}{3}x+3$$\frac{4}{3}x=3$$x = \frac{9}{4}$Then plug in the x value into one of the original equations to find y:$y= \frac{9}{4}$
