If a line is perpendicular to the line 5x - y = 0 and forms a triangle...
To find the equation of the line that is perpendicular to the line 5x - y = 0, we need to find the slope of the given line and then find the negative reciprocal of that slope.

The given line can be rewritten in slope-intercept form as y = 5x.

The slope of this line is 5.

The negative reciprocal of 5 is -1/5.

So, the slope of the perpendicular line is -1/5.

Now, since the line forms a triangle of area 5 square units with the coordinate axes, we can use the formula for the area of a triangle: A = (1/2)bh, where A is the area, b is the base, and h is the height.

In this case, the triangle has a base of 5 units (since the x-intercept of the line is 5) and a height of 5 units (since the y-intercept of the line is 5).

Plugging these values into the area formula, we get:

5 = (1/2)(5)(h)

Simplifying, we get:

5 = (5/2)(h)

Dividing both sides by (5/2), we get:

h = 2

So, the height of the triangle is 2 units.

Now, we can use the point-slope form of a linear equation to find the equation of the perpendicular line. The point-slope form is y - y₁ = m(x - x₁), where (x₁, y₁) is a point on the line and m is the slope of the line.

Let's use the point (0, 2) as the point on the line.

Plugging in the values, we get:

y - 2 = (-1/5)(x - 0)

Simplifying, we get:

y - 2 = (-1/5)x

Adding 2 to both sides, we get:

y = (-1/5)x + 2

So, the equation of the line that is perpendicular to the line 5x - y = 0 and forms a triangle of area 5 square units with the coordinate axes is y = (-1/5)x + 2. Therefore, the correct option is a) 5y = -x + 10.
