<span>Given that, y = mx + b ...... (1) then the point-slope form make sense as a name for, y - y1 = m(x-x1) .......(2) Equation (1) we get, y = mx + b b = y - mx ....... (3) m is a slope b is the y-intersect (x1,y1) is the points Solve the equation (2), y - y1 = m(x - x1) y - y1 = mx - mx1 y = mx - mx1 + y1 y = mx + (y1 - mx1) y = mx + b ......... (4) (use equation (3)) Therefore we prove the y = mx - b</span>

Name the shapes that make up the Texas state flag. Are any of the shapes regular polygons? Explain.
Vesnalui [34]
3 rectangles. 1 star. The star is regular because all sides are of equal length and all angles are equal. The rectangles aren't regular because they have unequal sides when their angles are equal. P.S This is my first time answering a question. Don't be mad if its wrong.
