Show that the distance between the points (x,y) and the line Ax + By + C = 0 is: D = (Ax + By + C) / sqrt(A^2 + B^2) So, would you start out by multiplying sqrt (A^2 + B^2) to both sides and then it would become: sqrt (A^2 + B^2)D = Ax + By + C Then square

1-Explain how you can use a number line to show that 3/6 and 1/2 are equivalent fractions. my son write- you can show these fractions are equivalent because if the numerator is half of the denomirator it can be 1/2 so 3/6 is just like 1/2. so that's why

HOw do I make a table of values for y equals 3/2? Am I supposed to plot 3/2 on the graph and then draw a line? I know on the y side of the table I'm supposed to have 3/2, but I don't understand how to do the table of values.
