COMPREHENSIVE ANSWER DIGEST
◉distance from a to b. Answer: √(x2 − x1)^2 + (y2 − y1)^2
◉perpendicular lines. Answer: Lines that intersect to form right
angles
m1*m2 = -1
◉midpoint of the segment AB. Answer: (x1+x2/2, y1+y2/2)
◉point-slope form. Answer: y-y1=m(x-x1)
◉intersecting lines. Answer: a+b=180
◉slope intercept form. Answer: y=mx+b, where m is the slope and b
is the y-intercept of the line.
◉transversal. Answer: eight angles are formed when a line crosses
two parallel lines. the four big angles (a) are equal, and the four
small angles (b) are equal
, ◉parabola. Answer: y=ax^2+bx+c
