Question

Given the point (3, 22.50) and a slope of 7.5, which equation would be the correct point-slope form?

A) y - 22.50 = 7.5(x - 3)
B) y - 3 = 7.5(x - 22.50)
C) y - 7.5 = 3(x - 22.50)
D) y - 22.50 = 3(x - 7.5)

Answer 1

The correct point-slope form equation for the given point (3, 22.50) and slope of 7.5 is option A) y - 22.50 = 7.5(x - 3).

Step-by-step explanation:

Point-slope form of a linear equation is given by 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, (x1, y1) = (3, 22.50) and m = 7.5, so the equation becomes: y - 22.50 = 7.5(x - 3).
