Help me please

Select 2 statements that are true about the equation y+6=-10(x-3).1) the slope of the line is -102) the slope of the line is 33) one point on the line is (3,6)4) one point on the line is (3,-6)

Give me the equations of two lines that have the same slope but are not parallel.

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