Math Problem Statement

There is a line that includes the point (-3, -4) and has a slope of -5/4. What is its equation in point-slope form?

Solution

The problem asks for the equation of a line in point-slope form given the point (3,4)(-3, -4) and the slope m=54m = -\frac{5}{4}.

The point-slope form of a line is written as: yy1=m(xx1)y - y_1 = m(x - x_1) where (x1,y1)(x_1, y_1) is a point on the line and mm is the slope.

Here, the point (3,4)(-3, -4) means x1=3x_1 = -3 and y1=4y_1 = -4, and the slope m=54m = -\frac{5}{4}.

Substituting these values into the point-slope form: y(4)=54(x(3))y - (-4) = -\frac{5}{4}(x - (-3))

This simplifies to: y+4=54(x+3)y + 4 = -\frac{5}{4}(x + 3)

Thus, the equation in point-slope form is: y+4=54(x+3)y + 4 = -\frac{5}{4}(x + 3)
