How do I find the slope point equation of this when I only have (4,-2) and no slope?

Need ! give step by step solutions on how to solve number one [tex]\frac{9-2\sqrt{3} }{12+\sqrt{3} }[/tex] number two [tex]x+4=\sqrt{13x-20}[/tex] number three (domain and range) [tex]f(x)=2\sqrt[3]{x} +1[/tex]

Multiply. write your answer in simplest form. 3/8 x 5/7

What additional information could be used to prove abc =mqr using sas? check all that apply.
