If varies inversely as b and a=12 when b=4 find a when b=-16

Solve this equation using substitution. {4x + y = −2} {4x + 6y = 44}

Which statements are true? check all that apply. the line x = 0 is perpendicular to the line y = –3. all lines that are parallel to the y-axis are vertical lines. all lines that are perpendicular to the x-axis have a slope of 0. the equation of the line parallel to the x-axis that passes through the point (2, –6) is x = 2. the equation of the line perpendicular to the y-axis that passes through the point (–5, 1) is y = 1.

0if x and y vary inversely and y=6 as x=7, what is the constant of variation?
