A(5,0) and B(3, 4) are two points. (i) Find the equation of the line through
A and B.
(ii) Investigate which of the following
points are not on the line in part (i):
C(4,2) D(1,8) E(3,5) F(-4,7)

yes   because as the functions are graphed they eventually will intersect unless otherwise

step-by-step explanation:

1. 180°. the sum of the interior angles of a triangle is 180°, for the equilateral triangle that it has three equals side is 60°+60°+60°=180°.

2. 60°. each interior angle of a equilateral triangle is 60°

3. 120°. the measure of ∠m is 120°, the sum of the angles ∠m and ∠n is equal to 180°. so, in order to find the measure of ∠m, we have ∠m+∠n=180° > ∠m=180°-∠n > ∠m=180°-60°=120°.

4. 360°. the sum of the exterior angles of an equilateral triangle is ∠m+∠r+∠x=120°+120°+120°=360°. the exterior angles of any triangle always add 360°.

the solution, from the graphing of the two lines, is (3,2), i.e., x = 3, y = 2.
