The coordinates of the points P, Q and R are given by (-2, 1), (1, 4) and (4, k) respectively. Find the value(s) of k if
(a) P, Q and R lie on the same line (clue: gradient);
(b) PQ=QR (clue: distance).

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.

answer: (x+2) (x+3) are the binomials for your question : )

answer: b for

so pick b if you want the right answer

step-by-step explanation: i really don’t know but i think it b because like i just know it b
