(parsed from the explanation — this source omits an answer key
for this item)
Explanation
The correct answer is 2. The slope-intercept form of an equation for a line is , where m is the slope and b is the y-coordinate of the y-intercept. Two ordered pairs, and , can be used to compute the slope using the formula . It’s given that and ; therefore, the two ordered pairs for this line are and . Substituting these values for and gives , or 2.
