Find values of a and b that make the following equality into identity:

Evaluate the given expression if m=45 |-3m|

Asystem of equations has 1 solution.if 4x-y=5 is one of the equations , which could be the other equation ?

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.
