two point formula
find slope m
Two Point Slope Form Definition: Two Point Slope Form is used to generate the Equation of a straight line passing through the two given points. Two Point Form Formula: Two Point form where (x1, y1) and (x2, y2)are the two given points,
You've got 2 equations and 2 unknowns. Your line can be written as an equation of the form y = mx + d. Now you know 2 points (6, -3) and (-4, -9) that satisfy this equation. Substitute x= 6 and y= -3 into y=mx + d to get the first equation, substitute x=-4, y= -9 to get the second equation: \[y= mx + d\]\[1) -3 = m\cdot 6 + d\]\[2) -9 =m\cdot (-4) + d\]
(y-y1)/ (y2-y1) = (x-x1)/ x2-x1) y1 =-3; y2 = 9; x1 = 6; x2 = -4 solve it
(y+3)/12 = (x-6)/-10 cross multiply
we get -10y -30 = 12x -72 12x +10y =42 6x+5y = 21 is the equation
hope u got it
okie
there are 2 points given .. right ??
oh let me see again then .. can u gimme the options plzz
sorry i took y2 = 9 instead of -9
last option
i simplified it further
y+3 =3/5(x-6)
do u need the detailed solution ??
sure
