Answer:
Step-by-step explanation:
If a point (x, y) lies on a straight line, coordinates of the point will satisfy the equation.
Slope of a line passing through two points C(4, 5) and D(8, 10),
m =
m =
m =
Equation of the line passing through C(4, 5) and slope m =
y - y' = m(x - x')
y - 5 =
y =
y =
If point B(4, 0) lies on the line CD,
0 =
0 = 5
Which is not true.
Therefore, point B doesn't lie on line CD.
namely, let's rationalize the denominator in the fraction, for which case we'll be using the <u>conjugate</u> of that denominator, so we'll multiply top and bottom by its <u>conjugate</u>.
so the denominator is 5 + i, simply enough, its conjugate is just 5 - i, recall that same/same = 1, thus (5-i)/(5-i) = 1, and any expression multiplied by 1 is just itself, so we're not really changing the fraction per se.
