Given a right triangle with legs a and b and hypotenuse c, find the lengths of side b if: a=2 root 3, c=2b PLEASE HELP

Itook a better photo of the question so y’all can see it i hope it’s a fine photo

The slope of a line is –2 and its y-intercept is (0, 3). what is the equation of the line that is parallel to the first line and passes through (2, 2)? a. 2x + y = 6 b. y = –2x + 3 c.y=1/2x +6 d.y=-2x-6

Which of the following represents the range of the graph of f(x) below
