Question

Which is the equation of the line that passes through the point (2, -2) and has a slope

of 3?
y= 223 +2
y = 2x + 3
y = 3x - 8
y = 3x - 2

Answer 1

The answer is

y = 3x - 8

Explanation:

To find an equation of a line when 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, -2) and slope is 3

The equation is

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

We have the final answer as

y = 3x - 8

Hope this helps you
