Answer: y - 4 = 2 (x + 1)
Explanation:
There are in four general forms of equations:
- Slope-intercept form: y = mx + b
- Point-slope form: y - y₁ = m (x - x₁)
- Standard form: Ax + By = C
- Intercept form: x/a + y/b = 1
Here, we are going to use the point-slope form because the question has given us both the slope and one point.
Solve:
**Disclaimer** Since the question did not clarify, thus, I choose to use the point-slope form as it is the easiest method. However, if the question has a specified form of the equation, please tell me and I will redo it.
Given information
(x₁, y₁) = (-1, 4)
m = 2
Given expression
y - y₁ = m (x - x₁)
Substitute values into the expression
y - 4 = 2 (x + 1)
Hope this helps!! :)
