Question

find the equation of the line passing through points A(3,4) and B(1,10)​

Answer 1

Answer:

y = -3x + 13

Step-by-step explanation:

First, find the slope:

$m=\frac{y_1-y_2}{x_1-x_2}\\\\m=\frac{4-10}{3-1}\\\\m=\frac{-6}{2}\\\\m=-3$

Finally, find the equation:

$y-y_1=m(x-x_1)\\\\y-4=-3(x-3)\\\\y-4=-3x+9\\\\y=-3x+13$
