Given the point:

(-4, 27)

Let's determine the equation of a line that is parallel to (y = -4 + 1) amd passes through the given point.

Apply the slope intercept form of a linear equstion:

y = mx + b

Where:

• m is the slope

,

• b is the y-intercept.

Here, we have:

y = -4x + 1

Where:

• Slope = -4

,

• y-intercept = 1

Parallel lines have equal slopes.

Since parallel lines have the same slope, the slope of the line parallel to the given line is also -4.

Now, substitute -4 for m, and input the values of the point for x and y in (y = mx + b) to solve for b.

(x, y) ==> (-4, 27)

y = mx + b

27 = -4(-4) + b

27 = 16 + b

Subtract 16 from both sides:

27 - 16 = 16 - 16 + b

11 = b

b = 11

Therefore, the equation of the parallel line is:

y = -4x + 11

ANSWER:


y=-4x+11
