In △abc the points m and n belong to the sides
ac and ab respectively. am/mc = an/nb = 2/3 .
prove that mn∥bc. find mn, if bc=20. !

What is the y-intercept of the line given by the equation

Divide. write in the simplest form. 4 1/6 divided by 10

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.
