For number 19:
"at least 150" means either 150 ≤ ? or ? ≥ 150

plus 3 so +3x

The answer would be 150 ≤ 100 + 3x

Number 20:

A is at -2.5. The inverse is the opposite so 2.5

What is the slope of the line through the points (-2, -1) and (4, 3)?

Natalka [10]

Answer:

#2 option: $\frac{2}{3}$

Step-by-step explanation:

$slope=\frac{rise}{run} =\frac{y^2-y^1}{x^2-x^1}$

$\frac{3-(-1)}{4-(-2)}=\frac{-4}{-6} =\frac{-2}{-3} =\frac{2}{3}$

= $\frac{2}{3}$
