Final answer:
None of the provided equations represent a vertical line which would be perpendicular to the horizontal line represented by y = 15 / 8. Thus, none of the equations is perpendicular to the given line.
Step-by-step explanation:
To determine which line is perpendicular to the given equation, we need to understand the concept of slope. For the equation 5y + 3y = 15, simplifying it first will give us y = 15 / (5 + 3), simplifying further we get y = 15 / 8. This implies the slope is 0 since the equation is now y = constant, which is a horizontal line.
Now, looking at the provided choices:
- 3x + 5y = 10
- 10x - 6y = 18
- Y + 5 = -3
- Y = -3x + 10
The slopes of these lines, when put in slope-intercept form (y = mx + b), are as follows:
- m = -3/5 for the first equation,
- m = 10/6 for the second equation,
- m = 0 for the third equation (which is a horizontal line and thus parallel to the given line),
- m = -3 for the fourth equation.
Since a horizontal line is perpendicular to a vertical line, we look for the equation that represents a vertical line (m is undefined). Therefore, none of the provided equations are perpendicular to the given equation y = 15 / 8, since they all have defined slopes.
