Help!!!!!! show all work

Gnom [1K]

Hi There!

----------------------------------------------

Part A:

Slope Intercept Form: y = mx + b

m = slope (slope = $\frac{y2 - y1}{x2 - x1}$ )

b = y intercept

$m=\frac{4 - 6}{(-2)- (-6)} = \frac{-2}{4} = \frac{-1}{2}$

b = 3

Answer: y = -1/2x + 3

----------------------------------------------

Part B:

Just substitue f(x) for y.

Function Notation = f(x) -1/2 + 3

----------------------------------------------

Part C:

This function given looks almost the same but the slope is different while the one stated in the question has a slope of +2 and the equation given at the start with the slope being -1/2.
