A line passes through the points (3, 21) and (6,24). write a linear function rule in terms of x and y for this line

Find the slope of a line given the following two points

In the figure below, ∠dec ≅ ∠dce, ∠b ≅ ∠f, and segment df is congruent to segment bd. point c is the point of intersection between segment ag and segment bd, while point e is the point of intersection between segment ag and segment df. the figure shows a polygon comprised of three triangles, abc, dec, and gfe. prove δabc ≅ δgfe.

Complete the solution of the equation. find the value of y when x equals -5. -4x - 8y = -52
