$\sf y = mx + b$ is the slope intercept form of a line, where m is the slope

 (given  by: $\sf \large m=\frac{y_2-y_1}{x_2-x_1}$ ) and b is the y-intercept (0, y).

anonymous · Answer

so pick two points from the table and solve for the slope first.

directrix · Answer

I went over to the online calculator to crank out the equation of the line from the given points. http://www.webmath.com/equline1.html Enter two points and an explanation and the equation appear.

directrix · Answer

The equation the program cranked out is one of the options.
