There are 5 questions i need with,

What is the point-slope form of theequation for the line with a slope of-2 that passes through (1, 4)? a y + 1 = -2(x + 4)b y-1=-2(x-4)c y + 4 = -2(x + 1)d y - 4 = -2(x - 1)

What is the distance between the points (2 -3) and (-6 4) on the coordinate plane

The angle of a triangle are given as 6x,(x-3), and (3x+7). find x then find the measures of the angles
