Question

the slope of the line passing through the points (7,5)and(21,15) is

Answer 1

y=$\frac{5}{7}$x+0 is the equation. $\frac{5}{7}$ is the slope.

Answer 2

Answer:

The slope is $\frac{5}{7}$

Step-by-step explanation:

Since, the slope of a line that passes through the points $(x_1,y_1)$ and $(x_2,y_2)$ is,

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

Thus, the slope of the line passes through the points (7,5) and (21,15) is,

$m=\frac{15-5}{21-7}$

$=\frac{10}{14}$

$\implies m=\frac{5}{7}$
