Write the equation of the line that passes through the points (7,-6) and (0,2). Put
Alex

Answer:

y+6=\frac{-8}{7} (x-7)

Step-by-step explanation:

To find the slope of the equation use \frac{y_2-y_1}{x_2-x_1}.

So, \frac{-6-2}{7-0} = \frac{-8}{7}. Now we can use our slope and any of the two points to write in point-slope form, which is y-y_1=m(x-x_1). Using the point (7,-6), the formula will give y+6=\frac{-8}{7} (x-7).

To check, you can plug in this equation and the points into a calculator to graph. The line passes through both points.
