Question

Find the equation of the line that passes through the point (-2,-7) that has a slope of 3

Answer 1

The answer is

y = 3x -1

Explanation:

To find an equation of a linewhen given the slope and a point we use the formula

`y - y_1 = m(x - x_1) \\`

where

m is the slope

( x1 , y1) is the point

From the question the point is (-2,-7) and slope 3 is

The equation of the line is

`y + 7 = 3(x + 2) \\ y + 7 = 3x + 6 \\ y = 3x + 6 - 7`

We have the final answer as

y = 3x - 1
