We can determine the equation of a line using the slope-intercept form, y = mx + b, where m is the slope of the line and b is the y-intercept. In Figure 1A.5.1, we can see that the y-intercept is 1.5 and the slope is 0.5. Therefore, the equation of the line is y = 0.5x + 1.5, which is equivalent to y = 1.5 + 0.5x. Choice C is the best choice as it represents the equation in the standard form of y = mx + b.
