Question

What is the equation of the line, in point-slope form, that passes through the points (-3, -1) and (-6, 8)? open study?

Answer 1

إ

Hello : let A(-3,-1) B(-6,8)
the slope is : (YB - YA)/(XB -XA)
(8+1)/(-6+3) =9/(-3)
the slope is: -3

the equation of the line, in point-slope form is : y - 8 = - 3(x +6)
