Question

Find the equation of the line show

Answer 1

Answer:

Equation : y = 2x + 3

Step-by-step explanation:

By considering any two coordinates from the line.

For example: I choose (0, 3) and (2, 7)

slope :

$slope = \frac{y_2 - y_1}{x_2 - x_1} = \frac{7-3}{2-0} = \frac{4}{2} = 2$

Equation :

$(y - y_1) = m (x - x_1)\\\\(y - 7) = 2 (x - 2)\\\\y - 7 = 2x - 4\\\\y = 2x - 4 + 7 \\\\y = 2x + 3$
