Work out the gradients of these lines: a. y = 2x + 5 b. y = x

Question:

Work out the gradients of these lines:


a. y = −2x + 5 


b. y = −x + 7 


c. y = 4 + 3x


d. y = 1/3x − 2 


e. y = −2/3x


f.


image


g. 2x − 4y + 5 = 0 


h. 10x − 5y + 1 = 0 


i. −x + 2y − 4 = 0


j. −3x + 6y + 7 = 0 


k. 4x + 2y − 9 = 0 


l. 9x + 6y + 2 = 0
