The number line below represents which combined inequality? a. x greater than or equal to −2 or x less than or equal to 4 b. x greater than or equal to −2 and x less than or equal to 4 c. x less than or equal to −2 or x greater than or equal to 4 d. x less than or equal to −2 and x greater than or equal to 4

Given the system of equations presented here: 2x + 4y = 14 4x + y = 20 which of the following actions creates an equivalent system such that, when combined with the other equation, one of the variables is eliminated? multiply the second equation by â’4 to get â’16x â’ 4y = â’80 multiply the second equation by â’1 to get â’4x â’ y = â’20 multiply the first equation by 2 to get 4x + 8y = 28 multiply the first equation by â’1 to get â’2x â’ 4y = â’14

What is the slope of the line that contains the points (-5, 6) and (14. - 7)?
