Just find the y intercept for both lines and calculate the change in y with respect to the x axis, aka slope. You can write an equation from any line by doing what I just said. The y-intercept is the y value where the function intercepts the y-axis.
Red Line: Y-intercept = 2 Slope = 1/1
Blue Line: Y-intercept = 4 Slope = -1/2
And you should know the equation, atleast I hope you do. y = mx + b m being the slope b being the y-intercept
You now got: y = x + 2 and y = -(1/2)x + 4
Make them equal to each other since they are both equal to y. Solve for x and then solve for the actual y value. I don’t want to do everything for you, since you wouldn’t really learn anything
