Answer:

$y = \dfrac{1}{2}x-4$

Step-by-step explanation:

<h2>Equation of line in slope y-intercept form:</h2>

$\sf slope = m =\dfrac{1}{2}\\\\Point (2, -3) ; x_1 = 2 \ \& y_1 = -3\\\\\boxed{\bf y - y_1 =m(x -x_1)}$

$\sf y - [-3] = \dfrac{1}{2}(x - 2)\\\\y + 3 = \dfrac{1}{2}x - 2*\dfrac{1}{2}\\\\y + 3 = \dfrac{1}{2}x-1\\\\$

$\sf y = \dfrac{1}{2}x - 1 - 3\\\\ y =\dfrac{1}{2}x-4$

Let f(x) = 2x+4. If f(x) = 16, find x.

jeyben [28]

$f(x)=2x+4$

And we are given that $f(x)=16$ and want to find the value of x. Set f(x) to 16 and we get the equation:

$2x+4=16$

Subtract both sides by 4

$2x=12$

Divide both sides by 2

$x=6$

This is the answer. Let me know if you need any clarifications, thanks!
