What are the domain and range of h(x) = 3|x|? Group of answer choices

domain: all real numbers; range: y ≤ 0

domain: x ≥ 0; range: all real numbers

domain: x ≤ 0; range: all real numbers

domain: all real numbers; range: y ≥ 0

Lindsay used two points, (x,y; ) and (+2.82), to find the equation of the line, y = mx + b, that passes through the points. y2-y, first, she used the definition of slope and determined that the value of mis x, - . given this information, which expression must represent the value of b?

One line passes through (-7,-4) and (5,4) . another line passes through the point (-4,6) and (6,-9)

Hi, can anyone show me how to do this problem? 100 points for this. in advance
