Question

What is the slope of the line passing through the points (−1, 7) and (4, −1)?

Answer 1

Answer:

$- 1.6$

Step-by-step explanation:

To find the slope, use the equation

$\frac{y2 - y1}{x2 - x1}$

where (-1, 7) and (4, -1) is (x1, y1) and (x2, y2) respectively.

Hence, the slope will be

$\frac{ - 1 - 7}{4 - ( - 1)}$

Simplify:

$\frac{ - 8}{5}$

or

$- 1.6$

Answer 2

Answer:

$m=-1.6$

Step-by-step explanation:

We are asked to find the slope of line passing through the points (−1, 7) and (4, −1).

We will use slope formula to solve our given problem.

$m=\frac{y_2-y_1}{x_2-x_1}$, where,

$m$ = Slope of line,

$y_2-y_1$ = Difference between two y-coordinates,

$x_2-x_1$ = Difference between two x-coordinates of same y-coordinates.

Substitute the given values:

$m=\frac{-1-7}{4-(-1)}$

$m=\frac{-8}{4+1}$

$m=\frac{-8}{5}$

$m=-1.6$

Therefore, the slope of line passing through the given points would be $-1.6$.
