Let’s use y as a replacement for a number. You would do 3y-7 since you multiply by three and take away seven.
First set up a proportion
240/160 = 320/200
Cross multiply and if the left equals the right it is similar.
All it is asking is to plug the given x values into the equation (which are 0, 2, 4) and see what you get for y.
4y - 2x =16
4y - 2 (0) = 16
4y = 16
y = 4
4y - 2 (2) = 16
4y - 4 = 16
4y = 20
y = 5
4y - 2 (4) = 16
4y - 8 = 16
4y = 24
y = 6
so D
