Answer:
y - 8 = m(x + 10)
Explanation:
Use the standard point-slope form of the equation of a straight line:
y - k = m(x - h), where (h, k) is a point on the line.
Thus, we have y - 8 = m(x + 10).
Sounds like a line was given; if that's the case, please share it. We'd get the slope value (m) from this given line.
