Question

all formula coordinate geometry plz​

Answer 1

Answer:

√[(x2 − x1)2 + (y2 − y1)2] is Distance formula

Answer 2

$\mathtt{\huge{\orange{\underline{\underline{Answer :}}}}}$

• General Form of a Line [Ax + By + C = 0]

• Slope Intercept Form of a Line y [= mx + c]

• Point-Slope Form [y − y1= m(x − x1)]

• The slope of a Line Using Coordinates m [Δy/Δx = (y2 − y1)/(x2 − x1)]

• The slope of a Line Using General Equation m [−(A/B)]

• Intercept-Intercept Form [x/a + y/b = 1]

• Distance Formula [|P1P2| = √[(x2 − x1)2 + (y2 − y1)2]]

• For Parallel Lines, [m1 = m2]

• For Perpendicular Lines, [m1m2 = -1]

• Midpoint Formula M [(x, y) = [½(x1 + x2), ½(y1 + y2)]]

• Angle Formula [ tan θ = [(m1 – m2)/ 1 + m1m2]]

• Area of a Triangle Formula [ ½ |x1(y2−y3)+x2(y3–y1)+x3(y1–y2)|]

• Distance from a Point to a Line [ d = [|Ax0 + By0 + C| / √(A2 + B2)]]
