Below are sample questions representative of the exercises included on this worksheet and related 8.51 Finding a Missing Coordinate Using Slope skill assessments:

Problem 1Difficulty: Hard
Segment AB goes from (2, 5) to (8, 14). Segment CD goes from (-1, 0) to (x, 9). If the segments have the same slope, what is x?
Solution & Explanation:First find the slope of AB: (14 - 5)/(8 - 2) = 3/2. Segment CD must have the same slope, so its x-change is (9 - 0) / 3/2 = 6. Starting from -1, the missing x-coordinate is 5.
Problem 2Difficulty: Hard
Point C = (z, 3) is on the same line as A(-4, 8) and B(0, 6). Determine z.
Solution & Explanation:Collinear points have the same slope. First, slope AB = (6 - 8)/(0 - (-4)) = -1/2. From y = 6 to y = 3 is a change of -3, so the x-change must be -3 / -1/2 = 6. Therefore z = 6.
Problem 3Difficulty: Hard
The line with y-intercept -2 has slope 5/3. Find the x-coordinate of the point (x, 8) on this line.
Solution & Explanation:The line has equation y = 5/3x - 2. Substitute y = 8 and solve: 8 = 5/3x - 2. This gives x = 6.
