Quadratics Test!

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

Simultaneous Equations Know what simultaneous equations are Understand what they represent on a graph about line equations Be able to find co-ordinates of intersections

Solving Linear Equations Graphically Bilborough College Maths: core 1 solving linear equations simultaneously (Adrian) 13/01/2018 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) Bilborough College Maths: core 1 solving linear equations simultaneously (Adrian) 13/01/2018 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

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

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

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

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

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