Question

err well it says write the equation y=mx+c but the thing is the subjects alredy 'y' so i dont know if im meant to just simplify it or something. i alredy know how to find out the gradient and the coordinate so thats not neccesseryyyy. just need help on how to write the equation for each of demmm tyy

Answer 1

a) y = (10x + 18) ÷ 2

b) y = (35x + 70) ÷ 5

c) y = (18x + 12) ÷ 3

d) y = (49x + 21) ÷ 7

e) y = (42x + 17) ÷ 2

f) y = (10x + 22) ÷ 4

g) y = (33x + 19) ÷ 5

h) y = (11x + 3) ÷ 7
