Question
Write the equation of the line in point-slope form that passes through the point (4, -7) and has the slope -1/4.
- y +7 = -1/4(x - 4)
- y - 4 = -1/4(x + 7)
- y + 4 = -1/4(x - 7)
- y - 7 = -1/4(x - 4)
Hint:
Given point (x1, y1) and slope m
The equation will be y - y1 = m (x - x1)
The correct answer is: y +7 = -1/4(x - 4)
The given point (4, -7) slope m = -1/4
The point –slope form of linear equation is represented by y - y1 = m (x - x1), where m is the slope.
Step1: Substitute point and slope in equation.
y +7 = -1/4(x - 4).
y +7 = -1/4(x - 4) is the desired equation in slope-point form.
The equation will be y - y1 = m (x - x1)
