Question

coordinate geometry formulas pls​

Answer 1

Step-by-step explanation:

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)]]
