y=-x+4 y=2x+5 Slope of line 1 = -2, 4 is y intercept Slope of line 2= 2, 5 is y intercept. Intersection of lines is solution.

so how would that look on a graph? what would the coordinates be?

i know their intersecting lines, just unsure of the coordinates..

Either read it off the graph, or if they're in between points, y1=y2 -x+4=2x+5 Solve for x, plug into equation for y coord.

@nukka , typo first line should be "y = -x +2"
