Question

Line AB contains points A(4,5) and B(9,7).What is the slope of AB

Answer 1

$Slope = m = \frac{2}{5}$

Further explanation:

Let us define slope first.

"Slope is the measure of steepness of a line connecting two points"

Slope is denoted by m. The formula for slope for two points given is:

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

where (x1,y1) are the coordinates of one point and (x2,y2) are the coordinates of second point.

Here,

$A(4,5) = (x_1, y_1)\\B(9,7) = (x_2, y_2)$

Putting the values in the formula

$m = \frac{y_2-y_1}{x_2-x_1}\\= \frac{7-5}{9-4}\\=\frac{2}{5}$

Hence, the slope is 2/5.
