Question

Line ST and point V are shown on the graph.

On a coordinate plane, line S T goes through (negative 5, 0) and (5, 2). Point V is at (0, negative 2).

Line VW is to be drawn on the graph such that it is perpendicular to line ST. If the coordinates of point W are (−1, y), what is the value of y?

−7
−5
2
3

Answer 1

3

Explanation:

y + 2 = -5x

Substituting x = -1, we get:

y + 2 = 5

y = 5 - 2 = 3

Therefore, the value of y is 3. Answer: 3.
