The electricity goes out in a house. The temperature in the house changes by -8°F in 4 hours. On average, by how many degrees is the temperature
changing per hour?

What is the slope of the line that contains the points (4,8) and (9,8)? what type of line is it?

What are the solutions of the equation? 6x^2 + 11x + 4 = 0 a. 4/3, 1/2 b. -4/3, -1/2 c. 4/3, -1/2 d. -4/3, 1/2

The point a is at –2 and the point b is at 7. marissa would like to divide this line segment in a 4: 3 ratio, and she would like to use the formula x = (x2 – x1) + x1. what values should she substitute into the formula? a = a + b = x1 = x2 =
