What is the result of rotating the point (x, y) 90 degrees clockwise? i belive its (y,-x)

Find the equation of the line that goes through the points (4, –1) and (2, –5). use slope formula,equation,to find the slope of a line that passes through the points. m = use slope-intercept form, y = mx + b, to find the y-intercept (b) of the line. b = write the equation in slope-intercept form, y = mx + b.

How do i do this activity, is appreciated

If i have a 24 in loaf of bread and i cut it into two pieces one 9 in how long was the other
