Answer:
6
Step-by-step explanation:
60/6 = 10
6/6 = 1
1a. Y = mx + b
Y = 2x + b
-2 = 2(5) + b
-2 = 10 + b, b = 12
Equation: y = 2x + 12
1b. Standard form: Ax + By = C
subtract 12 and y from both sides
2x - y = -12
Equation: 2x - y = -12
Yes because 9+4 = 13 and if you plug in the y and x it turns out true
