Question

Write the equation of the line passing through the point (2,-4) with a slope of 3

Answer 1

Answer: $y = 3x - 10$

Step-by-step explanation:

The formula for calculating equation of a line when a point and slope is given is :

$y - y_{1}=m(x-x_{1})$

$x_{1}=2$

$y_{1}=-4$

$m=3$

substituting into the formula , we have

$y-(-4) = 3(x-2)$

$y+4=3x -6$

subtract 4 from both sides

$y = 3x - 10$

Answer 2

Answer:

Y= 3x + (-4)
