You're reproducing a 5 cm x 5 cm picture on a wall at a ratio of 1/3. How large is the surface you're reproducing it on?

We just started the introduction into circles and i have no idea how to do this.

Write an equation of the line that passes through 9,2 and is parallel to the line y=5/3x+9

Which statements about the system are true? check all that apply. y =1/3 x – 4 3y – x = –7 the system has one solution. the system consists of parallel lines. both lines have the same slope. both lines have the same y–intercept. the equations represent the same line. the lines intersect.
