Multiple similarity transformations are performed on a triangle. Which elements must be preserved?
ST
O orientation
O side length
O angle measure
O overall size

Side length!? I’m not tk sure

Where m is the slope of the line and b is the y-intercept of the line, or the y-coordinate of the point at which the line crosses the y-axis. to write an equation in slope-intercept form, given a graph of that equation, pick two points on the line and use them to find the slope. this is the value of m in the equation.
