You should be able to
find gradient using rise / run
identify the gradient and y-intercept from y = mx + c
form an linear equation given gradient and y-intercept and graph
Measures:
Gradient is a measure of steepness of a slope
Use of ratio to mesaure steepness
Functions and Models:
linear function - y = mx + c
model slopes of road in real life
Gradient
rise - vertical change
run - horizontal chane
positive and negative gradient
vertical line gradient
horizontal line gradient
