Find the x-intercept of the graph of the equation 𝘺=−𝟤.𝟨𝟧𝘹+𝟤𝟧. What does the x-intercept mean in terms of the situation?

Question

Answer 1

The x-intercept is the value of x when y=0. Therefore,

y = -2.65x + 25 1. Given

0 = -2.65x + 25 2. Set y=0

-25 = -2.65x 3. Subtract 25 from both sides.

(25/2.65) = x or x = 9.43 4. Divide -2.65 from both sides. A negative divided by a negative is a positive.
