Question

Which of the following points lies on the graph of this equation? y = 2x – 2 Select one: a. (-1, -1) b. (1, 0) c. (1, 4) d. (-1, -2)

Answer 1

For this case we have the following equation:
 y = 2x - 2
 For the point (1, 0) we have:
 x = 1
 y = 0
 Substituting values we have:
 0 = 2 (1) - 2
 0 = 2 - 2
 0 = 0
 We observe that equality is fulfilled and therefore, the point belongs to the equation.
 Answer:
 b. (1, 0)
