Every point on a line satisfies the equation of that line.
If two lines intersect at one point, that point is a point on both lines, so it must satisfy both lines. Since two different lines can intersect at most at one point, that point is the only point that makes the two equations true.

What is an equation of the line in point-slope form? How can the point-slope form be written in function notation?

harina [27]

The equation of a line in point slope form = $y - y_1 = m(x - x_1)$

To put $y - y_1 = m(x - x_1)$ into function notation, we need to get y by its self.
Lets say we had a point (2,2) and a slope of 3. Ok, now that we have our point and slope, lets turn point slope form into function notation.

$y - y_1 = m(x - x_1)$
$y - 2 = 3(x - 2)$
$y - 2 = 3x - 6$
$y = 3x - 6 + 2$
$y = 3x - 8$
Change the y to f(x)
$f(x) = 3x - 8$ <-----Function notation.

Answer and Step-by-step explanation:

A) The first three terms are:

5, 8, 11

B) The tenth term is 32

You find the answer by plugging in the value for n. So for A), you would plug in 1, 2, and 3 (the first 3 terms), then to find the tenth term, you plug in 10 for n.
