Answer:
The slope of the line passing thru (1,2) and (3,8) is 3.
Step-by-step explanation:
The slope of a line measures its degree of steepness and is sometimes referred to as the gradient. The general formula for slope is; change in y/change in x. In this case; slope = (8-2)/(3-1) =3
Answer:
3
Step-by-step explanation:
The steepness refers to the absolute value of the slope of the line.
Let [tex](x_1,y-1)=(1,2)[/tex] and [tex](x_2,y_2)=(3,8)[/tex].
Then the slope is given by the formula;
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
We substitute the values to obtain;
[tex]m=\frac{8-2}{3-1}[/tex]
[tex]m=\frac{6}{2}[/tex]
[tex]m=3[/tex]
The steepness is [tex]|3|=3[/tex]
