Two Line Eqn's.system%28y=5x%2B2%28EQN1%29%2Cy=2x-7%28EQN2%29%29
In EQN 1:
f%28y%29=0
0=5x%2B2
5x=-2------>cross%285%29x%2Fcross%285%29=-2%2F5
highlight%28x-2%2F5%29
f%28x%29=0
y=5%280%29%2B2=highlight%282=y%29
See graph:

In EQN 2:
f%28y%29=0
0=2x-7
2x=7------->cross%282%29x%2Fcross%282%29=7%2F2
highlight%28x=7%2F2%29
f%28x%29=0
y=2%280%29-7=highlight%28-7%29
See graph:
