Final answer:
The equation in point-slope form for a line with a slope of 0 that passes through (0, −10) is y = −10. This represents a horizontal line crossing the y-axis at −10.
Step-by-step explanation:
To write an equation in point-slope form for a line with a slope of 0 that passes through the point (0, −10), we use the point-slope formula:
y − y1 = m(x − x1)
Where (x1, y1) is a point on the line and m is the slope of the line.
In this case, the slope m is 0, and the point is (0, −10). Plugging these values into the formula:
y − (−10) = 0 ⋅ (x − 0)
This simplifies to:
y = −10
This equation represents a horizontal line that passes through (0, −10) on the y-axis.
