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
