A line has a slope of 8 and includes the points (1, z) and (2,8). What is the value of z?

NISA [10]

The value of z is zero

Step-by-step explanation:

The slope is the steepness of the line.

The formula for slope is given by:

$m=\frac{y_2-y_1}{x_2-x_1}\\Here\\(x_1,y_1)\ are\ the\ coordinates\ of\ first\ point\ on\ line\\(x_2,y_2)\ are\ the\ coordinates\ of\ second\ point\ on\ line$

Here

(x1,y1) = (1,z)

(x2,y2) = (2,8)

So,

$m=\frac{y_2-y_1}{x_2-x_1}\\8 = \frac{8-z}{2-1}\\8=\frac{8-z}{1}\\8-8 = -z\\z = 0$

The value of z is zero

What are the points of discontinuity y=(x-5)/x^2-6x+5?

ollegr [7]

$y = \frac{x - 5}{x^{2} - 6x + 5}$
$y = \frac{x - 5}{(x - 1)(x - 5)}$
$y = \frac{1}{x - 1}$

x - 1 = 0
+ 1 + 1
x = 1
