Two variables have a negative linear correlation. Is the slope of the regression line between these two variables positive or negative?

F(x)=x/2-2 and g(x)=2x^2+x-3 find (f+g)(x)

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.
