Gradient Intercept y = mx + c

Gradient of a line Graphs y = mx + c x y y intercept: where the graph cuts the Y axis Gradient: the slope (steepness) of the graph

Gradient of line Graphs rise run Positive gradient Negative gradient: Gradient Whole number gradient? 4= 2= -6= 1= Draw lines with these gradients 1) 2) 3) -4 4) 2 5) 1 6) *Pick any spot to start drawing gradient (no position without equation)!!

Gradient Intercept 1) Find and mark the y intercept ( c ) 2) From this point go across right then up/down to find gradient. (m) 3) Join these two points Eg 1) y = 2x + 3 3) y = ¼x – 2 2) y = 5x – 4 4) y = -3x + 5 y = mx + c
