Asked by Emre

Whats the equation which passes through (-3,-1 and (3,-4)?

To work out the equation of the line that passes through this point you know it will be in the form y=mx +c, where m is gradient of the line and c the y-intercept To work out the gradient, use the two points to calculate the change in y divided by the change in x, (-4-(-1))/(3-(-3)) = -3/6= -1/2 To work out the y intercept, y =-1/2x +.c plug in any of the co-ordinates on the line to work out c
