Answer:
y=3x-2
Step-by-step explanation:
The ordered pairs (0, -2), (1, 1), (2, 4), (3, 7) and (4, 10) represent a linear function, because 1-(-2)=4-1=7-4=10-7=3.
The equation for the unknown linear function is y=ax+b.
Then
1. -2=a·0+b, b=-2;
2. 1=a·1+b, a=1-b=1-(-2)=3.
Therefore, the equation is y=3x-2.
Answer:
y = (1.5x + 8)/6
Step-by-step explanation:
6y - 1.5x = 8
+1.5x +1.5x
6y = 1.5x + 8
---- ------------
6 6
y = (1.5x + 8)/6
