Find the equation of line passing through points a (1, 3) and b (3, 7).

Solution:

To find the equation of line passing through points A (1, 3) and B (3, 7).

we know that, to derive the equation of a line we first need to calculate the slope of the line. Slope m of a line at points and is given by - .

Slope of the line at point A(1,3) and B(3,7)

The equation of line passing through points A (1, 3) and B (3, 7) :

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
