Which is an equation in point-slope form for the line that passes through the points (−1,4) and (3,−4) ?

y+4=−2(x−3)

y−3=−2(x+4)

y+4=2(x−3)
y−4=2(x+3)

Can someone plz me understand how to do these. plz, show work.in exercises 1-4, rewrite the expression in rational exponent form.[tex]\sqrt[4]{625} \sqrt[3]{512} (\sqrt[5]{4} )³ (\sqrt[4]{15} )^{7}\\ (\sqrt[3]{27} )^{2}[/tex]
