Final answer:
By using the slope formula, the value of ‘k’ that ensures the line through (4, -4) and (k, -1) has a slope of ⅔ is determined to be 12.
Step-by-step explanation:
Finding the Value of ‘k’ for a Line with a Given Slope
To find the value of ‘k’ so that the line passing through the points (4, -4) and (k, -1) has a slope of ⅔, use the slope formula which is ⅔ = (y2 - y1) / (x2 - x1). In this case, (x1, y1) is (4, -4) and (x2, y2) is (k, -1), therefore:
(-1 - (-4)) / (k - 4) = ⅔
3 / (k - 4) = ⅔
Multiply both sides by (k - 4) to get:
3 = (⅔)(k - 4)
Now divide both sides by ⅔ to isolate ‘k’:
3 / (⅔) = k - 4
Add 4 to both sides to get the value of ‘k’:
3 / (⅔) + 4 = k
After calculating, we get:
k = 12
