HELP MATH FINAL!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Which is not true about x=27 a) it intersects the axis at 2 b) its slope is undefined c) it is horizontal d) it is vertical Simplify using the distributive property -2(3x-4) if y varies directly as x and y and y=36 when x=18, find the constant of variation and write the variation equation for this find the slope of a line through the points (1,-8) and (-3,2) which is the independent variable in this situation? the cost of a long distance telephone call increases with the number of minutes of the call

    x=27 means a vertical line at x=27 for every y

    so it does not intesept at x=2 its slope is not undefined and it not horizontal

    -2(3x-4) When using the distributive property, we're just going to distribute the -2 to 3x and -4. So, -2*3x and -2*-4 gives us: -6x+8

    x=27 is a vertical line whose slope is undefined. So that means that choice A is untrue and choice c is also untrue. Must be a typo somewhere.

    undefined would be if it not continous

    Then put c as the wrong answer since it is vertical and not horizontal. But it does not cross the axis at 2 either. Could it possibly be that the equation is x = 2?

    i would go with c too, since its the most obvious one
