2. The points P and Q have coordinates (-2,6) and (8,2) respectively
The points P and Q have coordinates (-2,6) and (8,2) respectively. The line R is a perpendicular bisector to PQ (passes through the mid-point of PQ.) Find an equation for R, giving your answer in the form of ax + by +c = 0 where a, b, and c are integers

Solving Linear Equations Graphically
y= 2x + 1
Only a single point exists where both x and y are equal
x = 2 ; y = 5
(2,5)
y= -x + 7

Solving Linear Equations Graphically (2)
Problems:-
tedious to draw
results aren’t accurate
need graph paper
an algebraic method overcomes these problems
Difficult to read accurately
y= 1/3x + 2
y= 1/4x + 4

8. Simultaneous Equations
When you have y = mx + c Because they’re both y =

9. Try one out
When you have y = mx + c Because they’re both y =

10. Simultaneous Equations
When you have ax + by = c Make x or y the same ‘size’

11. Try one out
When you have ax + by = c Make x or y the same ‘size’

12. Simultaneous Equations
When you have both y = mx +c & ax + by = c You make an expression for y, so sub. in y =
