Equation C and Equation D have (2, 12) as their solution. Substituting
(2, 12) into both equations satisfies the given point.
To determine which pair of equations has (2, 12) as its solution, substitute the coordinates (2, 12) into each equation and see which pair satisfies the given point.
1. Equation A:
y = mx + b
Substitute (2, 12):
12 = m(2) + b
Solve for m and b.
2. Equation B:
y = mx + b
Substitute (2, 12):
12 = m(2) + b
Solve for m and b.
3. Equation C:
y = mx + b
Substitute (2, 12):
12 = m(2) + b
Solve for m and b.
4. Equation D:
y = mx + b
Substitute (2, 12):
12 = m(2) + b
Solve for m and b.
Check which pair of equations yields the values of m and b consistent with the point (2, 12). The correct answer is Equation C and Equation D.
