Question

Sandy said that the lines y = x + 3 and y = -10 are perpendicular. Explain Sandy's error.

a) Sandy's statement is correct.
b) Sandy's statement is incorrect, and the lines are not perpendicular.
c) Sandy's statement is incorrect, and the lines are perpendicular.
d) Sandy's statement is ambiguous.

Answer 1

Sandy's statement is incorrect, and the lines are not perpendicular.

Step-by-step explanation:

Sandy's statement is incorrect, and the lines are not perpendicular. To determine if two lines are perpendicular, we need to consider their slopes. The slope of the line y = x + 3 is 1, while the slope of the line y = -10 is 0. Since the product of the slopes is not -1, the lines are not perpendicular.
