Re: Algebra II

(-4,7) and (2,-2)

d = √(x2 - x1)² + (y2 - y1)²
=  √[2 - (-4)]² + [-2 - 7]²
=  √6² + (-9)²
=  √36 + 81
=  √117
=  10.8

-------------------------------

Through (-5,8) and parallel to y = (3/5)x - 4

Parallel lines have equal slopes.

slope = 3/5  through (-5,8)

y = mx + b
8 = (3/5)(-5) + b
8 = -3 + b
b = 11

y = (3/5)x + 11
