Straight line graphs Flashcards
1
Q
straight line graph equation
A
y=mx+c
2
Q
y
A
altitude, y axis
3
Q
m
A
gradient of line, up is positive, down is negative
4
Q
x
A
on x axis, multiply to gradient
5
Q
c
A
where line intercepts
6
Q
how to work out gradient
A
change in y/change in x, go up and along using triangle method
7
Q
what is x if altitude (y) starts at 200m
A
0
8
Q
example of a slope
A
y (altitude)= 0.3 (gradient) x horizontal distance (x) + 200m (altitude)
9
Q
what happens if you go down slope 50m
A
0.3 x -50 + 200m
