the general equation is y= mx + c
form fist eqn by substituting y = -7 and x = 7
7m + c = -7 --------(1)
form the second eqn by substituting y=-3 and x = -4
-4m + c= -3 ----------(2)
solving the simultenous eqn
m = -4/11 and c =-17/11
substitute these values in y =mx +c
y = -4x/11 - 17/11
11y = -4x -17

first find the slope = y2-y1/x2-x1
-3-(-7)/-4-7 = 4/-11
y=-4/11x + b
-7 = -4/11(7) + b
b= 11/4
so equation = y= (-4/11)x + 11/4

FIRST FIND SLOPE WITCH IS +4/-7
THE POINTS SLOPE FORM OF A LINE IS
Y+7=-4/7(X-7)

I think it's X1-X2 / Y1-Y2 so uhmm It would be like...7-(-4)/-7-(-3) or something like that.

go to edit and tell me why your writing an equation like Y2-Y1
---------
X2-X1
?????????????????????????????????
