23 Find the equation of the line in slope-intercept form." 6 ту 4 2. Х 2 -6 -4 -2 4 6 --6 O y = 1/2x + 4 y = -2x - 4 2 y y = -4x - 2

Answer 1

y=-2x -4

1) Picking points (0,-4) and (-4,4)

We can find the slope using the slope formula:

$m=\frac{4+4}{-4-0}\Rightarrow m=\frac{8}{-4}=-2$

2) Let's plug one point and the slope into the slope-intercept formula:

y=mx+b

(0,-4)

-4 =-2(0) +b

-4=b

3) Hence, the rule of that function is y=-2x -4
