What is the format of an equation in point-slope form?

Slope: 4/9
Point: (- 7, 12)

Practice makes perfect
Equations in point-slope form follow a specific format. y- y_1= m(x- x_1)

Here, m is the slope and ( x_1, y_1) is a point on the line. Let's rewrite the given equation to match the above format. y-12= 4/9(x+7) ⇔ y- 12= 4/9(x-( - 7)) Now, we can identify the slope and one of the points. Slope:& 4/9 Point:& ( - 7, 12)
