Question 430526: Solve this linear equation by graphing both equations and showing point of intersection
y= x - 2
y= 5/2x + 1
Please tell me the exact coordinates where the two lines intersect
5/2 is the rise over run equation. Rise is 5 and run is 2 but i can't seem to get the above two equations to intersect

Hi
Solve this linear equation by graphing
y= x - 2 Pts (0,-2) and (2,0) on this line (Green)
y= 5/2x + 1 Pts (0,1) and (-2/5,0) on this line (Blue)
Line intersect at Pt(-2,-4)
Checking algebraically: x-2 = 2.5x+1 1.5x = -3 x = -2 and y = -2-2 = -4
