Question 1170003
Solve the following pair of equations graphically. 
2x - 3y = 1
1.25 x + 0.5y = 3
:
Put both equations in the slope intercept form; y = mx + b
-3y = -2x + 1
divide both sides by -3
y = {{{2/3}}}x - {{{1/3}}}
and
.5y = -1.25x + 3
divide both sides by .5
y = -2.5x + 6
:
Plot these two equations on your device
{{{ graph( 300, 200, -4, 10, -4, 10, .6667x-.3333, -2.5x+6) }}}
looks like x=2, y=1 is the solution, checks out in both equations
