Which equation in slope-intercept form describes the line shown in the graph below?

y = -2x - 1
y = -1/2x + 1
y = 2x - 1
y = 1/2x + 1

The correct answer is: y = -1/2x + 1

This equation is in slope-intercept form, y = mx + b. Option A has a slope of -2 and a y-intercept of -1, meaning the line would have a steeper slope and a lower y-intercept than the one shown in the graph. Option C also has a slope of 2, but it has a y-intercept of -1, which would result in a line with a steeper slope and a lower y-intercept than the one shown in the graph. Option D has a slope of 1/2 and a y-intercept of 1, meaning the line would have a shallower slope and a higher y-intercept than the one shown in the graph. Therefore, option B is the best fit for the line shown in the graph.
