Find the image of a(4, -2) after it is reflected over the line y= 2, then reflected over the line x = 2. (-8,6) o (0.-2) o (0,6) (-8, -2)

Find the slope and the y-intercept if there's one and the equation of the line given these two points( 3, 2) and( 3, -4)

True or false: the graph of y=f(bx) is a horizontal compression of the graph y=f(x) if b< 1
