## Algebra 1: Common Core (15th Edition)

Recall, the equation for point slope form is the following: $y- y_{1}=m(x - x_{1})$, where $(x_{1} , y_{1})$ is a point on the line and m is the slope of the line. In front of the parentheses, we see the number 4/9, so we know that this is the slope. y is being subtracted by 12, so we know that the y point is 12. We see that because 7 is being added to x, the x-value must be -7 (because a negative minus a negative is a positive). Thus, we find that a point on the line is (-7,12).
