Question 245492
5x - 2y = -1
-2y=-5x-1
y=-5x/-2-1/-2
y=5x/2+1/2 (red line)
0=5x/2+1/2
5x/2=-1/2
5x*2=2*-1
10x=-2
x=-2/10
x=-1/5 or (-1/5,0) x intercept.
y=5/2*0+1/2
y=1/2 or (0,1/2) y intercept.
-----------------------------
x + 4y = 35
4y=-x+35
y=-x/4+35/4 (green line)
0=-x/4+35/4
x/4=35/4
4x=4*35
4x=140
x=140/4
x=35 (35,0) x intercept.
y=-0/4+35/4
y=35/4
y=8.75 (0,8.75) y intercept.
