An equation that goes through (-2, 1) and has a slope of 4 is y = 4x + 9.

You can find this by looking for the y-intercept (b) by using the slope (m), the point and slope intercept form. The work is below for you.

y = mx + b

1 = 4(-2) + b

1 = -8 + b

9 = b

Now we can use that and the slope to create the equation y = 4x + 9

Determine the scale factor of the function f(x)=1/3root x

Travka [436]

Please be clear with the expressions.
Here we assume
f(x)=(1/3) sqrt(x)

A scale factor is a multiplier applied to a parent function.
If the parent function is f(x), and
g(x)=a*f(x), then a is a scale factor.

Assuming the parent function is sqrt(x), and f(x)=(1/3) sqrt(x)
then the scale factor is (1/3).
[note]
if f(x) is a cube root, then write
f(x)=cube root(x), or f(x)=x^(1/3).
the exponentiation sign ^ is very useful.
