Question

Hello, I need some assistance with this homework question please for precalculusHW 23

Answer 1

slope = 1

Step-by-step explanation

Given:

Points (1, 2) and (8, 9).

Desired Outcome:

Slope of the line

Applying the slope formula

`slope\text{ = }\frac{y_2\text{ - y}_1}{x_2\text{ - x}_1}`

where:

y2 = 9,

y1 = 2

x2 = 8 and

x1 = 1

Substituting the values

`\begin{gathered} slope\text{ = }\frac{9\text{ - 2}}{8\text{ - 1}} \\ slope\text{ = }(7)/(7) \\ slope\text{ = 1} \end{gathered}`

Hence, the slope of the line containing the points (1, 2) and (8, 9) is 1.
