Question 54781: a) write the slope-y-intercept equation form of line which passes through the 2 points: (-3,1), (0,6)
b) wrie the slope-y-intercept equation form of the line which has slop 2/3 and passes through the point: (-3,3)
c) write the point-slope equation form of the line which passes through the 2 points: (9,0), (-5,3)
d) write the general equation form of the line which passes through the 2 points: (1,2), (6,7)

You can put this solution on YOUR website! SEE THE FOLLOWING EXAMPLE AND TRY FOR SLOPE AND A POINT PROBLEM
FOR THE 2 POINT PROBLEM SOLUTION IS AS FOLLOWS.
------------------------------------------------------------------
a) Write the slope-y-intercept equation form of the line which passes through the 2 points: X1,Y1=(-3,1), (0,6)=X2,Y2
FORMULA IS
Y= (Y2-Y1)(X-X1)/(X2-X1)+Y1
Y=(6-1)(X+3)/((0+3) + 1
Y=5(X+3)/3 +1
Y=(5X/3)+ 6.................M=5/3=SLOPE.........6=Y INTERCEPT
----------------------------------------------------------------
use the given conditions to write an equation in the point-slope form and the slope-intercept form...thank you
slope=-2 = M , passing through (0, -3) = X1,Y1
FORMULA IS
Y=M(X-X1)+Y1
Y=-2(X-0)+(-3)= -2X-3
