Question

What is the equation of a line of slope of 4 and pass through (-1,-6)

Answer 1

The answer is

`\huge y = 4x - 2`

Explanation:

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

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

From the question the point is (-1,-6) and slope 4

The equation of the line is

`y + 6 = 4(x + 1) \\ y + 6 = 4x + 4 \\ y = 4x + 4 - 6`

We have the final answer as

`y = 4x - 2`

Hope this helps you
