One line passes through (-7,-4) and (5,4) . another line passes through the point (-4,6) and (6,-9)

Which expression gives you the distance between the points (5,1)and(9,-6)

Consider this equation. |y + 6| = 2 what can be concluded of the equation? check all that apply. there will be one solution. there will be two solutions. the solution to –(y + 6) = 2 will be also be a solution to the given absolute value equation. the solution(s) will be the number(s) on the number line 2 units away from –6. the value of y must be positive since the variable is inside absolute value signs.
