Final answer:
To find the missing coordinate between two points M (5,9) and B (-7,-7), one would typically use the midpoint formula. This involves averaging the x-coordinates and the y-coordinates. For M and B, the midpoint is calculated to be (-1,1).
Step-by-step explanation:
To find the missing coordinate given one point, such as point M (5,9) and point B (-7,-7), you need the appropriate mathematical formula. Let's assume you need to find the coordinate of a point that is in the middle of M and B. In this case, you would use the midpoint formula, which is derived from the average of the x-coordinates and the average of the y-coordinates of the two points.
The midpoint formula is given as:
( (x1 + x2)/2, (y1 + y2)/2 )
Applied to our points M and B, the calculations would be:
- x-coordinate: (5 + (-7))/2 = (-2)/2 = -1
- y-coordinate: (9 + (-7))/2 = 2/2 = 1
Therefore, the midpoint's coordinates are (-1,1).
If you need to find the missing coordinate assuming both points lie on a line, and you have the equation of that line in the slope-intercept form (y=mx+b), you would substitute the known x or y value into the equation and solve for the other variable. However, without an equation or another specific requirement, the midpoint formula is the standard approach for finding an intermediate point between two given points.
