Question 5824
first get this into the y=mx+c form, so that we then can know some things about the line...


4x+2y=8 --> subtract 4x from both sides
2y = -4x + 8 --> divide both sides by 2
y = -2x + 4


this is now in the y=mx+c form...where m=-2. This is the gradient.


Any line parallel to this one will have the same gradient, so our new streaight line will be y = -2x+c. What is the value of c?. Well to find that from this equation we need to know x and y...which we do. The question gave us (-1, 5). So,


5 = -2(-1) + c
5 = 2 + c
3 = c


--> equation of line is therefore y = -2x+3
