What is the x values such that y equals 15 - 3 x and y equals 0 question

Match each function with the corresponding function formula when h(x)=5-3x and g(x)=-3+5

Solve for x i'll try to attach the files bc it's not letting me for some reason

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.
