Question

An illustration shows a coordinate plane with four quadrants. The x-axis ranges from negative 3 to 3 in one unit increments. The y-axis ranges from negative 3 to 6 in one unit increments. A downward slanting line is graphed on the coordinate plane. The line passes through two plotted points. The points have coordinates at (-1, 4) and (1, 0).
Write the equation of the linear function shown on the graph.
A. y = 2x + 2
B. y = -2x + 2
C. y = -2x - 2
D. y = 3x - 2

Answer 1

Slope = (0 - 4)/(1 - (-1)) = -4/2 = -2. Use point (1,0): y - 0 = -2(x - 1) → y = -2x + 2. Answer: B.
