Enter your answer as an ordered pair. y = 2x - 3 y = -2x + 5 I mean you could just plot them out using... ...where is the slope and is the intercept. Or, add the equations like so: So, subbing back into your first equation gives The answer is

how ??
Choose some values to plug in to both equations, then find the corresponding values: .. .. .. Then, plot these coordinates on a graph for both equations. You want the point at which the two lines intersect.
it was incorrect
