Determine the domain and range of the given function. the domain is all real numbers all real numbers greater than or equal to –2{x: x = –2, –1, 0, 1, 2}{y: y = –2, –1, 0, 1, 2}. the range is all real numbers all real numbers greater than or equal to –2{x: x = –2, –1, 0, 1, 2}{y: y = –2, –1, 0, 1, 2}.

What is the equation of a line that passes through points (0, 4) and (-4,-8)?

How can you find the magnitude of a vector, v = < x,y > , where the horizontal change is x and the vertical change is y?
