Контрольные задания > The question is to match the graphs with the formulas. The graphs are labeled A, Б, and B. The formulas are numbered 1, 2, and 3.
Formulas:
1) y = -2x - 1
2) y = -2x + 1
3) y = 2x + 1
Graphs:
Graph A shows a line passing through approximately (0, -1) and (-0.5, 0).
Graph Б shows a line passing through approximately (0, 1) and (-0.5, 0).
Graph B shows a line passing through approximately (0, 1) and (0.5, 0).

Graph Б shows a line passing through approximately (0, 1) and (-0.5, 0).
Graph B shows a line passing through approximately (0, 1) and (0.5, 0).
Graph A: This line has a negative slope and a negative y-intercept. It passes through approximately (0, -1) and (-0.5, 0). This matches formula 1) \( y = -2x - 1 \).
Graph Б: This line has a negative slope and a positive y-intercept. It passes through approximately (0, 1) and (-0.5, 0). This matches formula 2) \( y = -2x + 1 \).
Graph B: This line has a positive slope and a positive y-intercept. It passes through approximately (0, 1) and (0.5, 0). This matches formula 3) \( y = 2x + 1 \).
