The equation of a line that passes through the point (-1,-4) and has a gradient of 2 is y = 2x - 2
<h3>How to find equation of a line?</h3>
The equation of a line can be represented as follows:
y = mx + b
where
- m = slope or gradient
- b = y-intercept
Therefore,
m = 2
y = 2x + b
-4 = 2(-1) + b
-4 + 2 = b
b = - 2
Therefore,
y = 2x - 2

Answer:
y= -(x+5)^2+4
Step-by-step explanation:
Use transformations
1/2n - 4 = 5
1/2n = 5 + 4
1/2n = 9
n = 9 * 2
n = 18 <==
