Maths (help)
The line joining (c,4) to (7,6) has a gradient -1/4
q) work out value of d
so I did 6-4 over 7-c which = -1/4
2 over 7-c = -1/4
How did get of the division? x but what?

x
Multiply both sides by (7-c). You can do anything in maths so long as you do it to both sides of the equation.

Yup, if c was not at the bottom then the question would be easy but i dont know what to do because how do you x -1/4(7-c)
