Answer:

$- 3x + 6 = 21$

$- 3x = 21 - 6$

$- 3x = 18$

$- 3x \div - 3 = 18 \div - 3$

$x = - 6$

$- 3x + 6 < 21$

$- 3x < 21 + 6$

$- 3x < 27$

$- 3x \div - 3 < 27 \div - 3$

$x > - 9$

Find x-intercept and y-intercept

x-intercept = 3 → (3, 0)

y-intercept = -6 → (0, -6)

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

Substitute:

$m=\dfrac{-6-0}{0-3}=\dfrac{-6}{-3}=2$
