Infinite Solutions

Explanation:

y=165-0.4 (x-10); y=165-0.4 (x-10)

Rewrite equations:

y=-0.4x+169; y=-0.4x+169

Step: Solve y=-0.4x+169for y:

y=-0.4x+169

Step: Substitute-0.4x+169 for y in y=-0.4x+169:

y=-0.4x+169

-0.4x+169=-0.4x+169

-0.4x+169+0.4x=-0.4x+169+0.4x (Add 0.4x to both sides)

169=169

169+-169=169+-169 (Add - 169 to both sides)

0=0

Therefore equation has infinite solutions

Y=165+(-.4)(x-10)y=165+(-.4)(x-10)
