What is the equation of a line that is parallel to y = −4x − 3 and shifted down 3 units?

Find an equation for the linear function which has slope -10 and x-intercept -7

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.

How do i simply this radical expression?
