Question

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)

Answer 1

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

Answer 2

4/5

Answer 3

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???

Answer 4

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

Answer 5

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

Answer 6

yep... good work.

Answer 7

thank you for helping me out :)
