FORM
o 𝒚 = 𝒎𝒙 + 𝒄
Where:
m is a gradient
c is y intercept
TO FIND GRADIENT (m)
𝒚 −𝒚
o 𝒎 = 𝒙𝟐−𝒙𝟏
𝟐 𝟏
INFORMATION FROM GRADIENT (m)
o m > 0 → straight line will be increasing ( / )
o m < 0 → straight line will be decreasing ( \ )
o m = 0 → straight line will be a horizontal line ( − )
(Distance between points can be found simple e.g distance AB = 𝑿𝒓𝒊𝒈𝒉𝒕 − 𝑿𝒍𝒆𝒇𝒕 )
o m = undefined → straight line will be vertical
(Distance between points can be found simple e.g distance AB = 𝒀𝒕𝒐𝒑 − 𝒀𝒃𝒐𝒕𝒕𝒐𝒎 )
o For parallel lines
𝒎𝟏 = 𝒎𝟐
.
o For perpendicular lines
𝒎𝟏 × 𝒎𝟐 = −𝟏
