y=2x-4 and y=x-3 graphically method

Answer 1

y=2x-4 is a straight line with slope =2 and y intercept =-4

y=x-3 is a straight line with slope =1 and y intercept =-3

graph them and their intersection point is (1,-2) = (x,y)

x=1, y=-2 is the solution to the system of two equations

algebraically set y=y

2x-4 = x-3

2x-x = -3+4

x =1

y=x-3=1-3=-2
