Answer:
y = x/3 + 7
Step-by-step explanation:
Use the equation: y - y1 = m(x - x1)
Plug in the given values into the equation:
y - 5 = (1/3)(x + 6)
Simplify the right side:
y - 5 = (x/3) + 2
Finally, add 5 to both sides:
y = x/3 + 7
Answer:
Step-by-step explanation:
<em>The question has missing options ; However, the question is still solvable</em>
Given
Direction = 2 units left
Required
Shift the function by 2 units in the x axis
The general format of shifting a function along the x axis (by the left) is as follows
Where c represents the direction;
Since , then
