find the slope of the line through each pair of points ( -5, 10) , (-16, 8)

Which number line represents the solution set for the inequality -1/2x> 24?

How do the definitions, properties, and postulates you've learned about line segments, parallel lines, and angles to define the shapes of polygons

If (x + 8) is a factor of f(x), which of the following must be true? both x = –8 and x = 8 are roots of f(x). neither x = –8 nor x = 8 is a root of f(x). f(–8) = 0 f(8) = 0
