A line contains the points (8, 9) and (–12, –7). Using point-slope form, write the equation of the line that is parallel to the given line and that passes through (–5, –15)

Question

anonymous · Answer

first, calculate the slope of the line through  (8, 9) and (–12, –7)... what is it?

anonymous · Answer

4/5

anonymous · Answer

good... so 4/5 is the slope of the line you want AND it needs to go through the point (-5,-15)...
plug this into the point-slope form and what u got???

anonymous · Answer

HINT:  point-slope form:  $\large y-y_0=m(x-x_0) $, where $\large (x_0,y_0) $ is the given point.

anonymous · Answer

y+15=4/5(x+5)

anonymous · Answer

yep... good work.
