A student is attempting to find the equation of a line given a point and the slope. Which of the following statements best applies to the sample mathematical work shown below?

Given (1, –2) with a slope of 2/3 I find the equation of the line by plugging the values I'm given into the slope intercept form of the equation. Thus I have 1=2/3 x(-2) + b which results in b = 7/3 Thus, the equation of the line is y= 2/3 x + 7/3
