Answer: The missing coordinate is (5.75, -6)
Explanation:
Substitute (a,2) into the equation y = 8x + b to get:
2 = 8a + b
Subtract 8a from both sides to get:
b = 2 - 8a
Substitute (5,-6) into the equation y = 8x + b to get:
-6 = 8(5) + b
Substitute 2 - 8a for b to get:
-6 = 8(5) + (2 - 8a)
Simplify the equation to get:
-6 = 40 - 8a
Add 8a to both sides to get:
-6 + 8a = 40
Simplify the equation to get:
8a = 46
Divide both sides by 8 to get:
a = 5.75
The missing coordinate is (5.75, -6)
