Answer:

$\boxed {\boxed {\sf y=\frac {1}{4}x-2}}$

Step-by-step explanation:

Since we are given a point and a slope, we can use the point-slope formula.

$y-y_1=m(x-x_1)$

where m is the slope and (x₁ , y₁) is the point the line passes through.

We know the point is (4, -1).

We have to find the slope. We know that the line is parallel to y=1/4x.

This line has a slope of 1/4 (1/4 is the coefficient of x), and parallel lines have the same slope. Therefore, the line we are finding also has a slope of 1/4.

So, we know that:

m=1/4
x₁= 4
y₁= -1

Substitute these values into the formula.

$y--1=\frac{1}{4}(x-4)$

Now we must put the equation into slope-intercept form, or y=mx+b. We have to isolate y on one side of the equation.

First, distribute the 1/4. Multiply each term inside the parentheses by 1/4.

$y--1=(\frac {1}{4}*x )+(\frac{1}{4} * -4)\\y+1= \frac {1}{4}x-1$

1 is being added to y. The inverse of addition is subtraction, so subtract 1 from both sides of the equation. This will leave the variable y by itself.

$y+1-1= \frac {1}{4}x-1-1$
