3. A line with a slope of passes through the point (10,-5).
Ronch [10]

The equation of the line is y = -3/2x + 10

<h3>How to determine the line equation?</h3>

The given parameters are:

Slope, m = -3/2

Point, (x, y) = (10, -5)

The line equation is represented as

y = mx + b

Substitute the given parameters in the equation

-5 = -3/2 * 10 + b

This gives

-5 = -15 + b

Add 15 to both sides

b = 10

So, we have:

y = -3/2x + 10

Hence, the equation of the line is y = -3/2x + 10
