Question

When the x-value is 100, what is the corresponding y-value? How do you know?

Answer 1

Answer: -6

Explanation:

Given: y = 100 - 2x

New: y = 100 - 2(x + 3)

= 100 - 2x - 6

= 94 - 2x

The original equation had a y-intercept of 100. The new equation has a y-intercept of 94. The y-value changes by -6 units.
