The graph which best represents the new function is: Y. a linear function on a coordinate plane that passes through (1, 3), (0, 0), and (-1, -3).
<h3>How to determine the graph of the new function?</h3>
First of all, we would determine the slope of the linear function as follows:
Slope, m = -⅓.
Multiplying by -9, the new slope is:
Slope = -⅓ × -9
Slope = 3.
For the equation of this line, we have:
y - y₁ = m(x - x₁)
y - 3 = -⅓(x - (-3))
y - 3 = -⅓x - 1
y = -⅓x - 1 + 3
y = -⅓x + 2
Increasing the y-value by 2, we have:
y + 2= -⅓x + 2
y = -⅓x + 2 - 2
y = -⅓x.
Therefore, we would have a linear function on a coordinate plane that passes through (1, 3), (0, 0), and (-1, -3).
