How can you use the properties of equality to write equivalent equations?

Which expression is equivalent to the expression shown?

(mc 02.03) what set of reflections and rotations would carry rectangle abcd onto itself? reflect over the y-axis, reflect over the x-axis, rotate 180° rotate 180°, reflect over the x-axis, reflect over the line y=x reflect over the x-axis, rotate 180°, reflect over the x-axis rotate 180, reflect over the y-axis, reflect over the line y=x

Which shows the first equation written in slope-intercept form? 1/2 (2y + 10) = 7x
