Question

Write an equation of the line that had a slope of -2 and passes through (4,-2)

Need help ASAP!!

Answer 1

The equation is y = -2x + 6.

Explanation:

Given that the slope-form equation is y = mx + b and the gradient is -2. So you have to find the value of b by substituting the coordinates into the equation :

`y = mx + b`

`let \: m = - 2,x = 4,y = - 2`

`- 2 = - 2(4) + b`

`- 2 = - 8 + b`

`b = 6`

`y = - 2x + 6`
