no need to calc the lengths in d)
•
in d) you only /2 on the second line, A is not the triangle area on line 1
•
in a) you could start with y-y1 = m*(x-x1) as its a standard line representation
•
in a) end Id get in the habit of making two positive coefficients, so multiply through by -1
•
b) is a write down, no working should be necessary.
•
in c) you go back to working with fractions for "a". Not wrong, but unnecessary.
