Ok so i have encountered a problem! The question is the points a(6,1) B(2,-1) (a) find eq of line for AB. I done this got the slope as -2/-4 or 1/2. and worked out the eq of line to be x -2y -4 =0 but the part b is where im finding difficulty it asks (b) The line AB crosses the y-axis at C. Find the co-ordinates of C. I don't know i was thinking that means the x=0 but don't know how to get the other value
