Answer:
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
