    -1 is the slope now write the equation of a line with slope -1 and that goes through the point -3,1

    parallel lines have the same slope, while perpendicular lines have the "oppsite reciprocal" slope which is another way to say when multiplied they equal to -1

    The way to find out between B and C is to plug in the point (-3,1)

    For example: b. y = -x - 2 b. 1=-(-3) -2 (-3,1) is in the form of (x,y) so we replace the x and y with those values

    so that means B is our answer since 1=1
