A 90 degree counter-clockwise rotation is being done on the black figure to get the red figure.
The algebraic rule for a 90 degree counter-clockwise rotation is
For instance, the point C = (0,1) moves to C' = (-1,0), which is shown in the graph given and also you can use the rule above to get the same coordinates. The other points A,B and D follow the same rule.
Side note: the rotation is centered at the origin (0,0). This point is fixed.
The slope of an equation is the number that comes before x. The slope of the line of 1/2x + 2y = 3 is 1/2. The slope of the line of 7 - 3y = 21.
These types of equations are a little tricker because they are not in slope-intercept form.
I hope I helped!
69.99
20% off of 14.99 is 119.992 then -50 is 69.992 but we round to nearest cent and sence 2 is less than five we round down so jt is 69.99$
