When asked to write a point slope equation for a line passing through the points (-4,-7) and (3,2) a student wrote y-2=-9/7(x-3). How can he fix this to write the correct equation
First let's find the slope Slope formula: [tex] \frac{y_2-y_1}{x_2-x_1} =slope[/tex] Given the two coordinates: (-4,-7) (3,2) x1,y1 x2,y2
Plug these numbers into the formula [tex] \frac{2-(-7)}{3-(-4)} = \frac{9}{7} [/tex] In this case the mistake that was made was that the student wrote the slope negative instead of positive Final answer: y-2=9/7(x-3)
